Question

A recent study gave the information shown in the table about ages of children receiving toys. The percentages represent all toys sold.

Age (years)	Percentage of Toys
2 and under 3-5 6-9 10-12 13 and over	20% 15% 30% 10% 25%

What is the probability that a toy is purchased for someone in the following age ranges?

(a) 6 years old or older
____%

(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 larger category.

(b) The 13-and-older category may include children up to 17 or 18 years old. This is a smaller category.

Answer 1

Answer)

A)

6 years or older = 30+10+25 = 65%

B)

12 or younger = 20+15+30+10 = 75%

C)

Between 6 and 12 = 30+10 = 40%

D)

Between 3 and 9 = 15+30 = 45%
