Q. A raffle has 1,000 tickets. One ticket will win a $820 prize. The rest will win nothing. If you have a ticket, what is the expected payoff?$____
Calculate Probability of Winning: Calculate the probability of winning the prize.Probability of winning = Number of winning tickets / Total number of ticketsProbability of winning = 10001
Calculate Probability of Losing: Calculate the probability of winning nothing.Probability of winning nothing = Number of losing tickets / Total number of ticketsProbability of winning nothing = 1000999
Determine Expected Payoff for Winning: Determine the expected payoff for winning the prize.Expected payoff for winning = Probability of winning ∗ Prize amountExpected payoff for winning = 10001∗$820Expected payoff for winning = $0.82
Determine Expected Payoff for Losing: Determine the expected payoff for winning nothing.Expected payoff for winning nothing = Probability of winning nothing × Prize amount for losingExpected payoff for winning nothing = 1000999×$0Expected payoff for winning nothing = $0
Calculate Total Expected Payoff: Calculate the total expected payoff.Total expected payoff = Expected payoff for winning + Expected payoff for winning nothingTotal expected payoff = $0.82 + $0Total expected payoff = $0.82
