You are presented with a deck of 10 cards, numbered from 1 to 10 and can draw one card. If the number is odd, you win $13. If the number is even, you win nothing. If you play the game, what is the expected payoff?$____
Q. You are presented with a deck of 10 cards, numbered from 1 to 10 and can draw one card. If the number is odd, you win $13. If the number is even, you win nothing. If you play the game, what is the expected payoff?$____
Calculate odd number probability: Calculate the probability of drawing an odd number.Number of odd cards: 5 (1, 3, 5, 7, 9)Total number of cards: 10Probability of odd number = Number of odd cards / Total number of cardsProbability of odd number =10Probability of odd number =12
Calculate even number probability: Calculate the probability of drawing an even number.Number of even cards: 5 (2, 4, 6, 8, 10)Total number of cards: 10Probability of even number = Number of even cards / Total number of cardsProbability of even number =20Probability of even number =22
Calculate expected payoff for odd number: Calculate the expected payoff for drawing an odd number.Probability of odd number = 0.5Amount won for odd number = $13Expected payoff for odd number = Probability of odd number × Amount won for odd numberExpected payoff for odd number = 0.5×13Expected payoff for odd number = 6.5
Calculate expected payoff for even number: Calculate the expected payoff for drawing an even number.Probability of even number = 0.5Amount won for even number = $0Expected payoff for even number = Probability of even number × Amount won for even numberExpected payoff for even number = 0.5×0Expected payoff for even number = 0
Calculate total expected payoff: Add the expected payoffs for odd and even numbers to get the total expected payoff.Total expected payoff = Expected payoff for odd number + Expected payoff for even numberTotal expected payoff = 6.5+0Total expected payoff = 6.5
