Solve the problem. Christmas lights are often designed with a series circuit. This means that when one light burns out the entire string of lights goes black. Suppose that the lights are designed so that the probability a bulb will last 2 years is 0.993 . The success or failure of a bulb is independent of the success or failure of other bulbs. What is the probability that at least one bulb out of 100 will burn out in 2 years? (Round to the nearest ten-thousandths.) 0.4954 0.0953 0.0506 0.5046
