Well, honey, with 3 numbers to choose from (3, 6, 9), you can make 6 combinations because you can arrange them in any order. So, it's like a little math party with 6 different ways to mix and match those digits. Hope that clears things up for ya!
To calculate the number of combinations that can be made with the numbers 3, 6, and 9, we can use the formula for combinations without repetition, which is nCr = n! / (r!(n-r)!). In this case, we have 3 numbers and we are choosing all of them, so n=3 and r=3. Plugging these values into the formula, we get 3C3 = 3! / (3!(3-3)!) = 6 / (6*1) = 1 combination. Therefore, there is only 1 combination that can be made with the numbers 3, 6, and 9.
6 of them.

There are 6!/3! = 120 different 3-digit numbers that can be made from these 6 digits.
10C6 = 10*9*8*7/(4*3*2*1) = 210 combinations.
6 different combinations can be made with 3 items
6 of them.

6! = 6*5*4*3*2*1 = 720
There are 6!/3! = 120 different 3-digit numbers that can be made from these 6 digits.
6 ways: 931,913,139,193,391,319
There are 6C3 = 20 such combinations.
3! or 6 combinations can be made from three distinct numbers. For this example they are: 345, 354, 534, 543, 435, 453.
7C3 = 7*6*5/(3*2*1) = 35 combinations.7C3 = 7*6*5/(3*2*1) = 35 combinations.7C3 = 7*6*5/(3*2*1) = 35 combinations.7C3 = 7*6*5/(3*2*1) = 35 combinations.
10C6 = 10*9*8*7/(4*3*2*1) = 210 combinations.
We select 1 shirt out of 6 shirts in (6 choose 1) ways or 6 ways. Then, we select 1 out of 3 pairs of shorts in (3 choose 1) or 3 ways. Therefore, the possible combinations of a shirt and a pair of shorts is 6 * 3 = 18 possible combinations.
