Four jelly beans are selected, one at a time from a bowl containing 6 black, 6 red and 6 green jelly beans. Let x represent the number of black jelly beans selected in 4 draws from the bowl.

(B) If this experiment is completed with replacement of the jelly beans, explain why x is a binomial random variable.
