Q. There are 10 cards in a hat, numbered 1 to 10. The game is to draw one card out of the hat. If the number you draw is even, you win $12. If the number you draw is odd, you win nothing. If you play the game, what is the expected payoff?$____
Game Payoff: question_prompt: What's the expected payoff for the game with the cards?
Card Distribution: There's 10 cards, 5 are even (2, 4, 6, 8, 10) and 5 are odd (1, 3, 5, 51, 52).
Winning Probability: You win $12 for even numbers, so the chance to win is 5 out of 10, or 21.
Expected Payoff Calculation: Expected payoff is calculated by multiplying the probability of winning p with the amount won x for each outcome, resulting in the formula p×x.
Expected Payoff: So, the expected payoff is 21 * $12 for the even numbers.
Math Calculation: Doing the math: 21 * $12 = $6.
