The time (in hours) that a certain component (which is frequently discharged into the atmosphere from jet fuel) remains toxic for some living beings, has a gamma distribution with parameters n = 10.1 and λ = 5.2. If we wish to obtain a probability of 0.83 from the bottom of the distribution, how many hours will the poison be harmful?
The probability of a customer arrival at a grocery service counter in any one second is equal to 0.4. Assume that customers arrive in a random stream, so an arrival in any one second is independent of all others. (Round your answers to four decimal places.) (a) Find the probability that the first arrival will occur during the sixth one-second interval. (b) Find the probability that the first arrival will not occur until at least the sixth one-second interval.
