Q. There are two different raffles you can enter.Raffle A has 250 tickets, and each costs $11. One ticket will win a $780 prize. The other tickets will win nothing.Out of 200 tickets in raffle B, each costing $17, one ticket will win a $340 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×$780)−(250249×$11)
Math Raffle A: Do the math for Raffle A.Expected value for Raffle A = $(3.12) - $(9.924)Expected value for Raffle A = -\$(\(6\).\(804\))
Calculate Expected Value Raffle B: Calculate the expected value for Raffle B.\(\newline\)Expected value for Raffle B = \(\frac{1}{200} * (\$340)\) - \(\frac{199}{200} * (\$17)\)
Math Raffle B: Do the math for Raffle B.\(\newline\)Expected value for Raffle B = \(\$(1.70)\) - \(\$(16.915)\)\(\newline\)Expected value for Raffle B = \(-\$(15.215)\)
