Explanation / Answer

1) A, all the 4 places can be occupied any of the 24 letters so 24x24x24x24

2) C, USA has 50 states: 62148/40 = 1242.96 So if all the states get 1242 it will be equal to 1242*50 = 62100. i.e. 48 extra X's, meaning several states will get 1243 X

3) C, probability exactly 2 spades is C(13 2) C(39 3) divided by total probability which is c(52 5)

4) A

p(F)=0.6
p(M)=0.4
p(Math and F)=0.5
p(Math and M)=0.75
