A company has installed a generator to back up the power in case there is a power failure. The probability that there will be a power failure during a snowstorm is .35. The probability that the generator will stop working during a snowstorm is .05. Find the probability that during a snowstorm the company will have at least one power source. Of course, the two power sources function independently.
I know I just need to multiply the probability of power failure during a snowstorm and probability the generator will stop working during the snowstorm, but how would I correctly set up the problem?
