Tennis shoes High heels 13 10 Under age 12 13 to 30 years old 31 to 50 years old 13 9 12 16 What is the probability that a randomly selected contestant is 13 to 30 years old and is no wearing tennis shoes? Simplify any fractions.

Answer 1

To find the probability of a randomly selected contestant to not be wearing tennis shoes we need to divide the number of contestans in that age range by the total number of contestants. This is shown below:

$p=\frac{9}{13+10+13+9+12+16}=\frac{9}{73}$

The probability is 9/73
