Answer 4

you'll use the n C r formula with n = 32 and r = 4

Answer 5

or you can think of it this way

4 slots: A,B,C,D

32 choices for slot A
31 for slot B
30 for slot C
29 for slot D


IF order mattered, then you'd have 32*31*30*29 = 863,040 different permutations

but order does not matter, so you have to divide that previous result by 4! = 24 to correct for overcounting.
