Among 500 randomly selected drivers in the 20-24 age bracket, 6 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 heor 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 thosein the 20-24 age bracket? Consider an event to be "unlikely" if its probability is less than or equal to 0.05.The probability that a randomly selected person in the 20-24 age bracket will be in a car crash this year is approximately(Type an integer or decimal rounded to the nearest thousandth as needed.)

Eleven percent of American children (ages 4 to 17) have Attention Deficient Hyperactivity Disorder (ADHD) according to the Center for Disease Control. Suppose six American children in this age group are randomly selected, is the probability that at least one has ADHD unusual? No, this probability is not unusual because it is more than 0.05. Yes, this probability is unusual because it is more than 0.05. No, this probability is not unusual because it is within 2 standard deviations of the mean.
