Question
In a box there are 3 red, 6 blue, and 9 yellow cards.
One card is picked up randomly. What is the probability that it is neither red nor yellow?Solution
Total number of cards = 3 + 6 + 9 = 18 Let E= event that the card drawn is neither red nor yellow = event that the card drawn is blue. ∴ n(E) = 6 ∴ P(E) = 6/18 = 1/3
