Question

among 300 randomly selected drivers in the 20 - 24 age bracket, 13 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 - 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.)

Explanation:

Step1: Recall probability formula

Probability $P(A)=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$

Step2: Identify values

The number of favorable outcomes (drivers in a car - crash) is $n = 13$, and the total number of outcomes (total drivers) is $N=300$.

Step3: Calculate probability

$P=\frac{n}{N}=\frac{13}{300}\approx0.043$

Answer:

$0.043$
