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

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. ======================== Cheers, Stan H.
