Question

In a box there are 6 red, 12 blue, and 18 yellow cards. One card is picked up randomly. What is the probability that it is neither red nor yellow?

A 3/4 Correct Answer Incorrect Answer
B 1/3 Correct Answer Incorrect Answer
C 5/3 Correct Answer Incorrect Answer
D 4/3 Correct Answer Incorrect Answer
E None of these Correct Answer Incorrect Answer

Solution

Total number of cards = 6 + 12 + 18 = 36 Let E= event that the card drawn is neither red nor yellow = event that the card drawn is blue. ∴ n(E) =12 ∴ P(E) = 12/36 = 1/3
