1. **State the problem:** You draw one coin from a bowl containing 13 pennies, 13 dimes, and 24 quarters. We want to find the expected value of the coin drawn.
2. **Formula for expected value:** The expected value $E$ is calculated as
$$E = \sum (\text{value of outcome} \times \text{probability of outcome})$$
3. **Calculate total number of coins:**
$$13 + 13 + 24 = 50$$
4. **Calculate probabilities:**
- Probability of penny: $\frac{13}{50}$
- Probability of dime: $\frac{13}{50}$
- Probability of quarter: $\frac{24}{50}$
5. **Assign values to coins:**
- Penny = 0.01
- Dime = 0.10
- Quarter = 0.25
6. **Calculate expected value:**
$$E = 0.01 \times \frac{13}{50} + 0.10 \times \frac{13}{50} + 0.25 \times \frac{24}{50}$$
7. **Calculate each term:**
$$0.01 \times \frac{13}{50} = \frac{0.13}{50} = 0.0026$$
$$0.10 \times \frac{13}{50} = \frac{1.3}{50} = 0.026$$
$$0.25 \times \frac{24}{50} = \frac{6}{50} = 0.12$$
8. **Sum the terms:**
$$E = 0.0026 + 0.026 + 0.12 = 0.1486$$
9. **Round to three decimal places:**
$$E \approx 0.149$$
**Final answer:** The expected value of the game is $0.149$.
