Question

1. Determine whether the situation is a permutation or a combination

Answer 1

1-b cuz its describing numbers
2-A-prmation again
3-7C5 = 7!/(5!2!) = 7*6/2 = 21 so its B
4-792
5-d
 hoped i helped

Answer 2

1) B combination because you are choosing 2 randomly

2) A permutation because you are arranging them in an certain order

3) B 7!/(5!(7-5)!) = 21

4) C 12C7 = 12!/(7!(12-7)!) = 792

5) D 10!/(2!(10-2)!) + 10!/(3!(10-3)!) = 165
