One guy handles equipment repair at a camera store. Repair time for cameras is exponentially distributed, with a mean of 1.6 hours per camera. Customers arrive with broken cameras at an average rate of 2.1 per eight-hour day. NOTE: calculate the measures per day.

Calculate the probability of two or more cameras in the system. (Do not round intermediate calculations. Round your answer to 4 decimal places.)
