Question

Among 350 randomly selected drivers in the 20 minus 24 age bracket, 11 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 20 minus 24 age bracket? Consider an event to be "unlikely" if its probability is less than or equal to 0.05.

Explanation / Answer

The probability that he or she will be in a car crash during the next year is 11/350 =0.031

Is it unlikely for a driver in that age bracket to be involved in a car crash during a year?

Answer: Yes, it would be unlikely.

Is the resulting value high enough to be of concern to those in the 20 minus 24 age bracket?
