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.

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%

step-by-step explanation:

this is not a question

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3
