Q. There are two different raffles you can enter.Raffle A, which is for a fundraiser, has 250 tickets. Each ticket costs $11. One ticket will win a $890 prize, and the remaining tickets will win nothing.Out of 500 tickets in raffle B, each costing $4, one ticket will win a $270 prize. The other tickets will win nothing.Which raffle is a better deal?(A)Raffle A(B)Raffle B
Calculate Expected Value Raffle A: Calculate the expected value for Raffle A.Expected value = (\text{Probability of winning} \times \text{Prize value}) - (\text{Probability of losing} \times \text{Cost per ticket})Expected value for Raffle A = (2501×$890)−(250249×$11)
Perform Calculations Raffle A: Perform the calculations for Raffle A.Expected value for Raffle A = ($3.56)−($9.90)Expected value for Raffle A = −$6.34
Calculate Expected Value Raffle B: Calculate the expected value for Raffle B. Expected value for Raffle B = 5001∗($270) - 500499∗($4)
Perform Calculations Raffle B: Perform the calculations for Raffle B.Expected value for Raffle B = ($0.54)−($3.996)Expected value for Raffle B = −$3.456
Compare Expected Values: Compare the expected values of both raffles to determine the better deal. Raffle A has an expected value of −$6.34, and Raffle B has an expected value of −$3.456.
Conclude Better Deal: Conclude which raffle is a better deal based on the higher expected value.Raffle B is a better deal because it has a less negative expected value.
