Suppose that the time (in hours) required to repair a machine is an exponentially distributed random variable with parameter λ (lambda) = 0.5.What's the probability that a repair takes less than 5 hours? AND what's the conditional probability that a repair takes at least 11 hours, given that it takes more than 8 hours?
Suppose that the time (in hours) required to repair a machine is an exponentially distributed random variable with parameter λ=0.8, i.e., mean = 1/lambda. What is (a) the probability that a repair takes less than 77 hours?

The time, in hours, required to fix a machine is an exponential variable with parameter λ = 1/2 (a) What is the probability that the repair time exceeds 2 hours? (b) What is the conditional probability that the repair time exceeds 10 hours, assuming it takes at least 9 hours?
Please help me find the correct answer to the problem with work as I am struggling and can't find it. 7. The time (in hours) required to repair a machine is an exponential distributed random variable with mean β= 2 hours. (b) What is the conditional probability that the repair takes at least 10 hours, given that its duration exceeds 9 hours?
