Among 400 randomly selected drivers in the 20-24 age bracket, 9 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 concern to those in the 20-24 age bracket? Consider an event to be "unlikely" if it's probability is less than or equal to 0.05
