Someone sells 2000 tickets for $1 each. Prizes are awarded of one $100, four $50, and eight $25. Find the expected value if you purchase 1 ticket.

Expected value is calculated by multiplying every possible outcome by its probability and then adding those products. Let's break this down. a) In this case there are 2000 outcomes. How...

Problem 10-15 Island Airlines Inc. needs to replace a short-haul commuter plane on one of its busier routes. Two aircraft are on the market that satisfy the general requirements of the route. One is more expensive than the other but has better fuel efficiency and load-bearing characteristics, which result in better long-term profitability. The useful life of both planes is expected to be about seven years, after which time both are assumed to have no value. Cash flow projections for...
