among 300 randomly tested drivers in the 16-18 age braket, 263 where in a car crash in the last year. If a driver in that age braket is randomly selected, what is the approximate probability that he or she will be in a car crash during the next year ? Is it unlikley for a driver in that age braket to be involved in a car crash during a year ? is the resulting value high enough to be a concern to thoes in the 16-18 age braket ? Consider an event to be "unlikley" if its probability is less than or equal to 0.05.   The probability that a rondomly selcted person in the 16-18 age braket will be in a car crash this year is approximatley?
