Question
A recent study gave the information shown in the table about ages of children receiving toys. The percentages represent all toys sold Percentage of Toys 1 5% 16% 23% 13% 3390 What is the probability that a toy is purchased for someone in the following age ranges? Age (years 2 and under 3-5 6-9 10-12 13 and over (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? The 13-and-older category may include children up to 17 or 18 years old. This is a smaller category The 13-and-older category may include children up to 17 or 18 years old. This is a larger categoryExplanation / Answer
Look at the table to answer every question
a)
P(6 years old or older)=23%+13%+33%=69%
b)
P(12 years old or younger)=100%-33%=67%
c)
P(between 6 and 12)=23%+13%=36%
d)
P(between 3 and 9)=16%+23%=39%
The 13 and older category may include children up to 17 or 18 years old. This is a large category.
