(b) 12 years old or younger

(c) between 6 and 12 years old

(d) between 3 and 9 years old

A child between 10 and 12 years old looks at this probability distribution and asks, "Why are people more likely to buy toys for kids older than I am (13 and over) than for kids in my age group (10–12)?" How would you respond?
a. The 13-and-older category may include children up to 17 or 18 years old. This is a smaller category.
b. The 13-and-older category may include children up to 17 or 18 years old. This is a larger category.

26%
Explanation / Answer
What is the probability that a toy is purchased for someone in the following age ranges?
(a) 6 years old or older = 25 + 12 + 26 = 63%
(b) 12 years old or younger = 19 + 18 + 25 + 12 = 74%
(c) between 6 and 12 years old = 25 + 12 = 37%
(d) between 3 and 9 years old = 18 + 25 = 43%
Last question
OPtion B is correct . The 13-and-older category may include children up to 17 or 18 years old. This is a larger category. As it contains age froups from 12 to 18 that contains children of age span of 6 years as compared to age span of 3 years for children in 10 to 12 age group.
