![### Calculating the Expected Value of a Card Game
In this exercise, we will determine the expected value for a game involving a standard 52-card deck. This will help us understand how much a player can expect to win or lose on average per game.
#### Game Rules:
1. A player must pay $14 to participate in the game.
2. The goal is to draw a card from a standard 52-card deck.
3. If a club is drawn (one of the 13 clubs in the deck), the player wins $21.
4. If any other suit is drawn (one of the 39 non-club cards), the player loses their $14.
#### Problem Statement:
Calculate the price that would make the game fair for the player.
#### Calculations:
1. **Determine the Probability of Each Outcome:**
- Probability of drawing a club (P(club)):
\[
\frac{13}{52} = \frac{1}{4} = 0.25
\]
- Probability of drawing a non-club (P(non-club)):
\[
\frac{39}{52} = \frac{3}{4} = 0.75
\]
2. **Calculate the Winnings and Losses:**
- Winning amount when a club is drawn: $21
- Loss amount when a non-club is drawn: $14
3. **Expected Value Calculation:**
The expected value (EV) is given by the formula:
\[
\text{EV} = (\text{P(club)} \times \text{Winnings}) + (\text{P(non-club)} \times \text{Loss})
\]
Substituting the probabilities and amounts:
\[
\text{EV} = (0.25 \times 21) + (0.75 \times (-14))
\]
\[
\text{EV} = (5.25) + (-10.5)
\]
\[
\text{EV} = -5.25
\]
4. **Fair Game Calculation:**
For the game to be fair, the expected value should be zero. Let "X" be the price that makes the game fair:
\[
0 = (0.25 \times 21) + (0.75 \](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F128593f5-7ea4-4e3b-94cd-55abf91c7165%2Ffbe59ff9-f48b-42c5-ba13-2c086f380bb0%2Far6rj0f_processed.jpeg&w=3840&q=75)
