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 a five-year-old son and a 13-year-old daughter, what is the probability of both children receiving a tablet?

a. 60%

b. 15%

c. 80%

d. 20%
