Final answer:
To make the game fair, you would need to lose 1/3 point for each of the other outcomes.
Step-by-step explanation:
To determine how many points you would need to lose for each of the other outcomes in order for the game to be fair, we need to calculate the probabilities of each outcome.
There are four possible outcomes when flipping two coins: HH, HT, TH, and TT. In this game, you win 1 point if both coins turn up tails (TT), so the probability of winning is 1/4.
For the game to be fair, the expected value should be 0. This means that the probability of winning 1 point should be equal to the probability of losing a certain number of points for the other outcomes.
Let's suppose you lose x points for each of the other outcomes. The expected value of the game is then:
- P(TT) * 1 - P(HH) * x - P(HT) * x - P(TH) * x = 0
- 1/4 - P(HH) * x - P(HT) * x - P(TH) * x = 0
Since the probabilities of flipping two heads (HH), a head and a tail (HT), and a tail and a head (TH) are all 1/4, the equation becomes:
- 1/4 - (1/4 * x) - (1/4 * x) - (1/4 * x) = 0
- 1/4 - 3/4 * x = 0
- -3/4 * x = -1/4
- x = (1/4) / (3/4) = 1/3
Therefore, you would need to lose 1/3 point for each of the other outcomes in order for the game to be fair.
