You volunteer to drive children at a charity event to the zoo, but you can fit only 6 of the 15 children present in your van. how many diferent groups of 6 children can you drive? how many dfferent groups of 6 children can you drive?

5005

Step-by-step explanation:

This is a concept of combinations and permutations which focus on the number of ways something can be done. Under permutations order matters and it can be easy to make the mistake of using the permutations (nPr)since the function is very similar to the combinations function (nCr), but here the order does not matter therefore can make use of combinations.

Therefore through using a calculator, 15 then press {2nd function} and press nCr, then press 6 (in other words, out of the 15 children present, we only want to choose 6) where order does not matter. Therefore there are 5005 different combinations of different groups of 6 children you can drive.
