Fido’s in the Car It seems that driving with a pet in the car is the third worst driving distraction, behind talking on the phone and texting.

According to an American Automobile Association study, 80% of drivers admit to driving with a pet in the car, and of those, 20% allow their dogs to sit on their laps.13 Suppose that you randomly select a sample of 100 drivers who have admitted to driving with a pet in their car.

a. What is the probability that 25% or more of the drivers allow their dogs to sit on their laps?

b. What is the probability that 10% or fewer of the drivers allow their dogs to sit on their laps?

c. Would it be unusual to find that 35% of the drivers allow their dogs to sit on their laps?
