Question

Among 400 randomly selected drivers in the 1618 age bracket, 227 were in a car crash in the last year. If a driver in that age bracket is randomly selected, what is the approximate probability that he or she will be in a car crash during the next year? Is it unlikely for a driver in that age bracket to be involved in a car crash during a year? Is the resulting value high enough to be of concern to those in the 1618 age bracket? Consider an event to be "unlikely" if its probability is less than or equal to 0.05.

Explanation / Answer

Approx probability of car crash = 227/400 = 0.5675 i.e. 56.75%

This probability is high enough to be of concern to those in 16-18 age bracket because the probability is not unlikely.
