A lottery has a grand prize of $100,000, two runner-up prizes of $12,500 each, four third-place prizes of $2000 each, and six consolation prizes of $200 each. If 200,000 tickets are sold for $1 each and the probability of any one ticket winning is the same as that of any other ticket winning, find the expected return on a $1 ticket. (Round your answer to two decimal places.)

$0.66

Explanation:

expected return of a lottery ticket equals the sum of the probabilities of winning each prize:

total expected value = $0.50 + $0.125 + $0.03 + $0.001 = $0.656 ≈ $0.66
