Question

The probability of a randomly selected car crashing during a year in a certain country is 0.04780.0478. if a family has three three ?cars, find the probability that at least one of them has a car crash during a year. is there any reason why the probability might be? wrong

Answer 1

We now that the probability that one randomly selected car will crash in the year is 0.047800478.
If a family has three cars, this means that the probability that some of their car will crash in the next year is : 3 * the probability that one randomly selected car will crash = 3 * 0.047800478. = 0.143401434
