Given that, among 450 randomly selected drivers in the 16 - 18 age bracket, 393 were in a car crash in the last year.
Here, probability = 393/450 = 0.873
Therefore,
The probability that a randomly selected person in the 16- 18 age bracket will be in a car crash this year is approximately 0.873
No, it is not unlikely. It would also not be unusual.
Yes, it is high enough to be of concern

14. In a survey, 161 respondents say that they never use a credit card, 1220 say that they use it sometimes, and 2828 say that they use it frequently. What is the probability that a randomly selected person uses a credit card frequently? Is it unlikely for someone to use a credit card frequently? How are all of these results affected by the fact that the responses were obtained by those who decided to respond to a survey posted on...
