Question

market research shows that 30% of consumers are likely to purchase an electronic tablet for younger children under 10. however, only 2% of consumers are likely to buy a laptop for children under age 10. on the other hand, for children ages 10 -17, 50% of consumers are likely to buy a tablet and 40% are likely to buy a laptop. if a family has five-year-old son and a 13-year-old daughter, what is the probability of both children receiving a tabletA. 60%B. 20%C. 15%D. 80%

Answer 1

0.15 (option C)

Step-by-step explanation:

Percentage of consumers likely to purchase an electronic tablet for younger children under 10 = 30%

percentage of consumers likely to buy a laptop for children under age 10 = 2%

percentage of consumers likely to buy a tablet for children ages 10 -17 = 50%

percentage of consumers likely to buy a laptop for children for children ages 10 -17 = 40%

A family has five-year-old son (under 10) and a 13-year-old daughter (10-17) and they want to get a tablet for both:

`\begin{gathered} \text{ the probability = 50\%}*30\text{\%} \\ =\text{ 0.5 }*\text{ 0.3} \\ \end{gathered}`
`\begin{gathered} \text{probabilty}=\text{ 0.15} \\ \text{probability = 0.15(option C)} \end{gathered}`
