Q. There are two different raffles you can enter. In raffle A, one ticket out of 100 will win a $370 prize. The other tickets will win nothing. Each ticket costs $15. Raffle B, which is for a fundraiser, has 200 tickets. Each ticket costs $16. One ticket will win a $680 prize, and the remaining tickets will win nothing. Which raffle is a better deal?(A)Raffle A(B)Raffle B
Calculate EVA for Raffle A: Calculate the expected value for Raffle A.Expected value (EVA) = (Prize amount ×Probability of winning) - Cost of ticket.EVA = ($370×1001) - $15.EVA = $3.70−$15.EVA = −$11.30.
Calculate EVB for Raffle B: Calculate the expected value for Raffle B.Expected value (EVB) = (Prize amount × Probability of winning) - Cost of ticket.EVB = ($680×2001) - $16.EVB = $3.40−$16.EVB = −$12.60.
Compare EV of Raffle A and Raffle B: Compare the expected values of Raffle A and Raffle B. Since −$11.30 is greater than −$12.60, Raffle A has a less negative expected value, making it the better deal.
