The correct answer is (D).
Getting to the Answer: There are 5 green jelly beans and a total of 4 + 5 + 3 = 12 red, green, and white jelly beans in the bag. Use the formula Probability = # of desired outcomes/# of total outcomes to determine the probability of randomly selecting a green jelly bean. That is 5/12/
(A) Incorrect: this would be the probability if there were only one green jelly bean
(B) Incorrect: this is the probability of selecting one green jelly bean out of a total of five green jelly beans
(C) Incorrect: this has the correct numerator, but the denominator is greater than the total number of jelly beans in the bag.
(D) Correct: this matches the correct calculation
(E) Incorrect: this is the ratio of green jelly beans to red and white jelly beans.
