You can play a game with a wheel whose rim is divided into equal sections marked with the numbers from 1 to 20. If you play, the attendant will spin the wheel and a ball will land in a random section. If the number the ball lands on is even, you win $18. If the number the ball lands on is odd, you win nothing. If you play the game, what is the expected payoff?$____
Q. You can play a game with a wheel whose rim is divided into equal sections marked with the numbers from 1 to 20. If you play, the attendant will spin the wheel and a ball will land in a random section. If the number the ball lands on is even, you win $18. If the number the ball lands on is odd, you win nothing. If you play the game, what is the expected payoff?$____
Question Prompt: question_prompt: What is the expected payoff for playing the game with the wheel?
Total Wheel Sections: There are 20 sections on the wheel, so there are 20 possible outcomes.
Number of Even Numbers: Half of the numbers from 1 to 20 are even, which means there are 10even numbers.
Probability of Winning: If the ball lands on an even number, you win $18. So the probability of winning $18 is 10 out of 20, or 21.
Calculate Expected Payoff: To find the expected payoff, multiply the amount won (18)bytheprobabilityofwinning(\frac{1}{2}$).
Final Expected Payoff: Expected payoff = \(\$18 \times \frac{1}{2}\)
