Answer:
5$
Step-by-step explanation:
1) The only way Miguel wins the 2 dollars is if he pulls the two chips with the number 1. There are four chips in total, so his probability of winning is:
2/4 * 1/3 = 1/6
The odds of losing a dollar is the compliment of this number, so 5/6.
2) Expected Value = (1/6)2 + (5/6)(-1) = -1/2
Miguel's expected loss is $-1/2 dollars each time he plays, although since this isn't actually a number he can lose, he should expect to lose a dollar each time he plays, which has a 5/6 chance of happening.
3) Let's set the expected value equal to zero, which implies a fair game, and Miguel' payout equal to X:
0 = (1/6)(x) + (5/6)(-1) Add 5/6 to both sides
5/6 = 1/6 (x) Multiply both sides by 6
30/6 = x
x = 5
The payout should be $5 in order to make the game fair.
