1. **State the problem:**
Calculate the expected value of a game where a card is drawn from a standard 52-card deck.
2. **Identify the outcomes and their probabilities:**
- Black face cards: There are 3 face cards (Jack, Queen, King) in each black suit (clubs and spades), so $3 \times 2 = 6$ cards.
- Red Aces: There are 2 red Aces (hearts and diamonds).
- Other cards: Total cards $52$ minus black face cards $6$ minus red Aces $2$ equals $44$ cards.
3. **Calculate probabilities:**
- $P(\text{black face card}) = \frac{6}{52}$
- $P(\text{red Ace}) = \frac{2}{52}$
- $P(\text{other card}) = \frac{44}{52}$
4. **Calculate expected winnings:**
$$E(\text{winnings}) = 40 \times \frac{6}{52} + 15 \times \frac{2}{52} + 8 \times \frac{44}{52}$$
5. **Calculate each term:**
$$40 \times \frac{6}{52} = \frac{240}{52}$$
$$15 \times \frac{2}{52} = \frac{30}{52}$$
$$8 \times \frac{44}{52} = \frac{352}{52}$$
6. **Sum the expected winnings:**
$$E(\text{winnings}) = \frac{240}{52} + \frac{30}{52} + \frac{352}{52} = \frac{622}{52}$$
7. **Simplify the fraction:**
$$\frac{622}{52} = \frac{\cancel{2}311}{\cancel{2}26}$$
8. **Calculate decimal value:**
$$\frac{311}{26} \approx 11.96$$
9. **Subtract the cost to play ($10$):**
$$E(\text{net}) = 11.96 - 10 = 1.96$$
**Final answer:** The expected value of the game is approximately $1.96$ per play, meaning on average the player gains $1.96$ per game.
