put this solution on YOUR website! Two jelly beans are selected, one at a time from a bowl containing 10 black, 10 red and 10 green jelly beans. Let x represent the number of black jelly beans selected in 2 draws from the bowl.
(A) If this experiment is completed without replacing the jelly beans, explain why x is not a binomial random variable.
The probability of selecting a black bean changes after each selection.
---------------------------------------------
(B) If this experiment is completed with replacement of the jelly beans, explain why x is a binomial random variable.
The probability of selecting a black bean is the same at each drawing.
