**Casino Game Expected Value Calculation**
**Problem Statement:**
A person must pay $10 to play a certain game at the casino. Each player has a probability of 0.03 of winning $13.
**Question:**
What is the Expected Value for the player (that is, the mean of the probability distribution)? If the Expected Value is negative, be sure to include the "-" sign with the answer. Express the answer with two decimal places.
**Calculation:**
- Expected Value (E) is calculated using the formula:
\[
E = ( \text{Probability of Winning} \times \text{Winnings} ) + ( \text{Probability of Losing} \times \text{Loss} )
\]
- Given:
- Probability of Winning = 0.03
- Winnings = $13
- Probability of Losing = 1 - 0.03 = 0.97
- Cost to Play (Loss) = -$10
Substitute these into the formula:
\[
E = (0.03 \times 13) + (0.97 \times -10) = 0.39 - 9.7 = -9.31
\]
The Expected Value is **-9.31**.
**Answer Validation:**
- The provided answer is marked incorrect with a red 'X'.
**Follow-up Question:**
If a person plays this game a very large number of times over the years, do we expect him/her to come out financially ahead or behind?
- Options:
- ☐ ahead
- ☑ behind
Selected answer: behind, marked correct with a green check.
