A property insurance company sells policies that cover flash flood, burglary, and lightning. If the probability of a house being burgled in a year is 1 in 100, the probability of it being struck by lightning in a year is 1 in 1,000 and the probability of it being affected by flash flood in a year is 5 times greater than that of being struck by lightning. Calculate the probability that the insurance company will end up paying for at least one of the events in a year time.
