A lottery has a grand prize of \$180,000, two runner-up prizes of \$22,500 each, eleven third-place prizes of \$3600 each, and fourteen consolation prizes of \$450 each. If 720,000 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.)

• Math -

(1/720,000)*180,000 + (2/720,000)*22,500 +(11/720,000)*3600 + (14/720,000)*450 = \$ 0.38
