Question

Your class is holding elections to choose a leadership committee of 4 students. If there are 30 students in the class, how many different leadership committees would it be possible to elect?

Answer 1

657,720?

Answer 2

a committee is a group of people, unranked, so the order doesn't matter in this case, so once again we will be using the combination formula

nCr = n! / r! (n - r)!

where n = the total # of people to choose from and r = the size of the committee

Answer 3

nCr = n! / [ r! (n - r)! ]

Answer 4

27405?

Answer 5

good

gotta go
