This probability distribution shows the typical distribution of the number of shoes in a teenager's closet. Using the distribution, find the probability that a teenager has 3 or fewer pairs of shoes in their closet.

Answer:
70%
Step-by-step explanation:
Total number of teenagers surveyed
12+20+38+20+10 = 100
Find the number of teenagers with 3 or fewer pairs of shoes
12+20+38 =70
P(3 or fewer) = teenagers with 3 or fewer/ total
= 70/100
= 70%
