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%
  • Total teenagers=12+20+38+20+10=90
  • Student having 3 or fewer pairs=12+20+38=70
