Question 1090870: The probability of a randomly selected car crashing during a year in a certain country is
0.0493
0.0493. 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?
The probability that at least one of them has a crash during the year is
nothing
.

You can put this solution on YOUR website! First, the probability of the cars NOT having a crash is 0.9507. So the probability that none will be in a crash is 0.9507^3, or 0.8169. The probability of at least one being in a crash would be 1-0.8169, or 0.1831. The probability may be wrong if the family does less driving that year; or drives in a particularly safe area, etc.
