It is estimated that there are 21 deaths for every 10 million people who use airplanes. A company that sells flight insurance provides $100,000 in case of death in a plane crash. A policy can be purchased for $1. Calculate the expected value and thereby determine how much the insurance company can make over the long run for each policy that it sells. The expected value is $1 (Round to the nearest cent.)

Answer:$0.79 profit per person who buys a policyStep-by-step explanation:For every 10 million people who buy a policy the expected outcome is $(21*100,000) = $2,100,000  (21 deaths out of 10 million)the expected income is  $10,000,000  ($1 per sold policy)So the expected profit is $10,000,000 - $2,100,000 = $7,900,000 To obtain how much the insurance company can make for each policy that it sells, we cross multiply 10,000,000 people ---------> $7,900,000 profit 1 person   -----------------------> x and 10,000,000=7,900,000/x and x = $0.79 profit per person who buys a policy
