Professor John is designing a water flask and he needs to know the probability that the filtration system will fail during a water cleaning. Based on previous data, Professor John estimates that the probability of a filtration system failure during the filtration cleaning is 0.05. If the water flask is used for 365 days in a year, what is the probability that the filtration system will not fail during any cleaning in a year?
A company offers guided tours of remote areas of the world. Each tour consists of 20 people. The probability of selling a ticket for any given spot on the tour is 0.86. The costs to the company are approximately the same regardless of the number of people that show up. To offset the risk associated with a tour not filling up, the company purchases a specialized insurance policy. The policy pays 100 for each ticket that is left unsold, up to a maximum of 400. Let P be the amount that the insurance policy pays to the company for a specific tour. Calculate E[P] to the nearest dollar. O 251 O244 O 259 O 267 275
