Online help is just a mouse click away. A permutation is an arrangement of all or part of a set of objects, with regard to the order of the arrangement. For example, suppose we have a set of three letters: A, B, and C.

We might ask how many ways we can arrange 2 letters from that set. Each possible arrangement would be an example of a permutation. When statisticians refer to permutations, they use a specific terminology.

They describe permutations as n distinct objects taken r at a time. Translation: n refers to the number of objects from which the permutation is formed; and r refers to the number of objects used to form the permutation.

Consider the example from the previous paragraph. For an example that counts permutations, see Sample Problem 1. A combination is a selection of all or part of a set of objects, without regard to the order in which objects are selected.

We might ask how many ways we can select 2 letters from that set. Each possible selection would be an example of a combination. When statisticians refer to combinations, they use a specific terminology. They describe combinations as n distinct objects taken r at a time.

Translation: n refers to the number of objects from which the combination is formed; and r refers to the number of objects used to form the combination. Note that AB and BA are considered to be one combination, because the order in which objects are selected does not matter. This is the key distinction between a combination and a permutation.

A combination focuses on the selection of objects without regard to the order in which they are selected. A permutation, in contrast, focuses on the arrangement of objects with regard to the order in which they are arranged. For an example that counts the number of combinations, see Sample Problem 2. The distinction between a combination and a permutation has to do with the sequence or order in which objects appear.

For example, consider the letters A and B. Using those letters, we can create two 2-letter permutations - AB and BA. Because order is important to a permutation, AB and BA are considered different permutations. However, AB and BA represent only one combination, because order is not important to a combination.

How many 3-digit numbers can be formed from the digits 1, 2, 3, 4, 5, 6, and 7, if each digit can be used only once? The solution to this problem involves counting the number of permutations of 7 distinct objects, taken 3 at a time. The number of permutations of n distinct objects, taken r at a time is:.

Thus, different 3-digit numbers can be formed from the digits 1, 2, 3, 4, 5, 6, and 7. To solve this problem using the Combination and Permutation Calculatordo the following:.

Is there a more efficient way to accomplish the same task? Yes, there does exist such a way. You first select 0 for d, then 1, and so on until you get to 7. List out the first sequence, Then list all the other numbers beneath them with the condition that for all numbers e and f, and with d held constant, the digits for e and f follow the natural number sequence down the column.

Partition each set of sequences by d. The column rule only applies within each partition. I guess the underlying idea I've used here lies in following the natural number sequence across the rows, and down the columns for the digits e and f also.

You have 10 options for the first, then 9 10 - the first for the second, and 8 for the third. Here is a link to a pre-publication fascicle:. Sign up to join this community.

Kutools for Excelwith more than handy functions, makes your jobs more easier. Free Download free full-featured in day.The Combinations Calculator will find the number of possible combinations that can be obtained by taking a sample of items from a larger set. Basically, it shows how many different possible subsets can be made from the larger set.

For this calculator, the order of the items chosen in the subset does not matter. Also referred to as r-combination or "n choose r" or the binomial coefficient. In some resources the notation uses k instead of r so you may see these referred to as k-combination or "n choose k.

You have won first place in a contest and are allowed to choose 2 prizes from a table that has 6 prizes numbered 1 through 6. How many different combinations of 2 prizes could you possibly choose? In this example, we are taking a subset of 2 prizes r from a larger set of 6 prizes n.

A teacher is going to choose 3 students from her class to compete in the spelling bee. She wants to figure out how many unique teams of 3 can be created from her class of In this example, we are taking a subset of 3 students r from a larger set of 25 students n.

First, let's find the total handshakes that are possible. That is to say, if each person shook hands once with every other person in the group, what is the total number of handshakes that occur? A way of considering this is that each person in the group will make a total of n-1 handshakes. Since there are n people, there would be n times n-1 total handshakes. In other words, the total number of people multiplied by the number of handshakes that each can make will be the total handshakes.

However, this includes each handshake twice 1 with 2, 2 with 1, 1 with 3, 3 with 1, 2 with 3 and 3 with 2 and since the orginal question wants to know how many different handshakes are possible we must divide by 2 to get the correct answer.

The order of the items chosen in the subset does not matter so for a group of 3 it will count 1 with 2, 1 with 3, and 2 with 3 but ignore 2 with 1, 3 with 1, and 3 with 2 because these last 3 are duplicates of the first 3 respectively.

For more information on combinations and binomial coefficients please see Wolfram MathWorld: Combination.If the digits can repeat, then there are possible combinations. If they can't repeat, then there are 24 possibilities. All the possible digits 10 of them; are multiplied by themselves by the number of digits that can be shown in the lock.

This certainly shows why guessing is not a good way to break into a numerical lock, especially since three is a rather low number of digits for one! In most 3-number locks, each number ring offers a choice of 10 digits, from 0 to 9.

I would have to say 10, possible combinations. Mrs Smith has nine children half of them are girls. Have you ever crashed a wedding or had your wedding crashed, if so what happened?

How many combinations can you make with the numbers 1,2,3?

Anonymous Jackson May Wiki User There are too many combinations to list.In a permutation order matters, so the permutation 1 2 3 is not the same as 2 1 3. In a combination order does not matter so the combination 2 3 is the same as 3 2. The question does not say whether we are allowed repetition or not. So we do not know whether we are to count 1 1 3 as a combination of 3.

We are also not told the size of the combination. But if repetition is allowed then there are infinitely many combinations of all sizes that can be formed. Therefore, I shall assume that repetition is not allowed.

Starting with 1 2 3 we can form combinations of size 1 2 or 3. For n things choosing r combinations we can count using the formula. That is a total of 7 combinations. If we wish to count choosing 0 items -- the empty combination -- as a combination, then we must add 1 way of doing that.

How many combinations can you make with the numbers 1,2,3? Mar 28, See a solution process below:. Explanation: The first number in the combination can be any 1 of the 3 number. The second number can be either of the 2 remaining numbers. For the final number you would have only 1 choice. Jim H. Please see below. Explanation: We are not told the size of the combinations to be formed. I'll return to this point later. Permutations and Combinations In a permutation order matters, so the permutation 1 2 3 is not the same as 2 1 3.

Combinations with or without repetition The question does not say whether we are allowed repetition or not. Without repetition Starting with 1 2 3 we can form combinations of size 1 2 or 3.I need to know all the possible 3 digit combinations using the numbers The numbers can be repeated as long as they are not of the same set. Example for not repeating: is ok but not or , etc. Please help me. Thanks, Mike. If order mattered, we would say select the first number 10 choicesthen the second 9 choices then the third 8 choices.

But because order does not matter, we have to take care of duplicates as you mentioned. How many duplicates are there for each set of three numbers? Well, again, we can choose one of the three as the "first", so there are 3 choices for that, then 2 choices for the "second" digit, then 1 choice for the last digit.

how many combinations with 3 numbers 0 9 list

Therefore in that set of possibilities, each unique combination of three digits is represented 6 times. So we just divide by 6. These are what are mathematically called "combinations". You can use a formula involving factorials to determine the number of combinations. In this case, we say this is "10 Choose 3" and write it as 10 C 3.

That means from a set of ten digits in this casechoose 3 regardless of order. For more information on Combinations and their close cousins Permutations where order matterslook up these words in our Quick Search. Math Central.
