ACT Question for April 18th

A bag contains 4 red jelly beans, 5 green jelly beans, and 3 white jelly beans. If a jelly bean is selected at random from the bag, what is the probability that the jelly bean selected is green?

A) 1/12

B) 1/5

C) 5/23

D) 5/12

E) 5/7

Correct

Incorrect

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
