You are going to play mini golf. A ball machine that contains 18
green golf balls, 19
red golf balls, 19
blue golf balls, and 20
yellow golf balls, randomly gives you your ball. What is the probability that you end up with a blue golf ball? Express your answer as a simplified fraction or a decimal rounded to four decimal places.
There are a total of 18 + 19 + 19 + 20 = 76 golf balls in the machine.
The probability of getting a blue golf ball is the number of blue golf balls divided by the total number of golf balls.
P(blue) = 19/76 = 0.2500
Therefore, the probability of ending up with a blue golf ball is 0.2500.
