Question

A golf ball is selected at random from a golf bag. If the golf bag contains 99 type A​ balls, 88 type B​ balls, and 44 type C​ balls, find the probability that the golf ball is not a type A ball.

Answer 1

4/7

Explanation:

To find the probability, we must first find the total number of golf balls. So 99+88+44 = 231 is our total. Now we must find the number of golf balls that are not a type A ball. This is just the total number of type B balls and type C balls. So 88+44 = 132. So the probability is 132/231. This simplifies to 12/21 or 4/7.
