- 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.
