a golf ball is selected at random from a golf bag. If the golf bag contains 4 brown balls, 9 yellow balls, and 12 orange balls, find the probability of the following event.

probability the ball is brown or yellow?

13/25

answer

To find the probability of the ball being brown or yellow, we need to determine the total number of balls in the golf bag and the number of brown and yellow balls.

The total number of balls in the golf bag is the sum of the number of brown, yellow, and orange balls: 4 + 9 + 12 = 25.

Now, to calculate the probability, we divide the number of brown or yellow balls (4 + 9 = 13) by the total number of balls (25):

P(Brown or Yellow) = (Number of Brown or Yellow Balls) / (Total Number of Balls)
= 13 / 25

Thus, the probability of selecting a brown or yellow ball is 13/25 or 0.52.
