A city is considering how much to spend to hire people to monitor its parking meters. The following information is available to the city manager: • Hiring each meter monitor costs $25,000 per year. With one monitoring person hired, the probability of getting a ticket each time one parks illegally is equal to 0.25. • With two monitors, the probability of getting a ticket is 0.50; with three monitors, the probability is 0.75, and with four, it's equal to 1.00...

Among 300 randomly selected drivers in the 16 minus 18 age bracket, 238 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...
