well there are 12 movies to choose from... 

so on the 1st choice 

P(action) = 4/12

now this is where it gets interesting.... for me.... the 2nd choice has  less movie to choose from.... so you are selecting from 11.... 

if you have already taken an action movie 

P(action) = 3/11

then the probability of selecting action + action is the product of the 2 probabilities. 

hope it helps
