A family has two cars that are insured, a sports car and a commuting vehicle. The probability that the sports car is in an accident in the next 4 years is 0.014. The probability that the commuting vehicle is in an accident in the next 4 years is 0.004. Assuming that accidents are independent events, compute the probability that at least one of the two cars is in an accident in the next 4 years. Use three decimal place accuracy.
