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.
