In a recent year, among 135,933,000 registered passenger cars in the United States, there were 10,427,000 crashes. Find the probability that a randomly selected passenger car in the United States will crash this year. Is it unlikely for a car to crash in a given year? What does this suggest about traveling?

Answer #1

Among 135,933,000 registered passenger cars in the United States, there were 10,427,000 crashes.

Therefore, the probability that a randomly selected passenger car in the United States will crash this year is:

P(crash)=\frac{10,427,000}{135,933,000}={\color{Red} 0.077}

Since this probability is greater than 0.05, it is NOT unlikely for a car to crash in a given year. This suggests that traveling is not safe.
