Answer:
Step-by-step explanation:
Using the expected value, it is found that you should charge $4 to have a fair game.
------------------------
- A probability is the <u>number of desired outcomes divided by the number of total outcomes</u>.
- The expected value is the <u>sum of each outcome multiplied by it's respective probability</u>.
- When you roll two dice, there are possible outcomes.
- We suppose a cost of x.
- In 6 of them, the sum is 7: (1,6), (2,5), (3,4), (4,3), (5,2) and (6,1).
- Thus, probability of earning a profit of 12 - x.
- 2 of them have sums of 2 or 12, which are (1,1) and (6,6).
- Then, probability of earning a profit of 36 - x.
- If the outcome is any of the remaining 28, the player loses, thus probability of losing x.
- The game is fair if the <u>expected value is 0</u>, then:
A value of $4 should be charged.
