Question

There are 24 marbles in a bag. There are 4 red, 8 blue, 10 green, and 2 yellow marbles. Find P(red u green).

Answer 1

7/12

Explanation:

The notation "P(red u green)" means the probability of drawing a red or green marble from the bag.

P(red) = 4/24 = 1/6

P(green) = 10/24 = 5/12

P(red u green) = 1/6 + 5/12 = 2/12 + 5/12 = 7/12

So, the probability is 7/12
