Probability Spade Jack
1. **Problem statement:** A card is drawn at random from a standard deck of 52 cards. We want to find the probability that the card is neither a spade nor a Jack.
2. **Formula for probability:**
$$\text{Probability} = \frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$$
3. **Step 1: Total number of cards**
There are 52 cards in total.
4. **Step 2: Count cards that are spades or Jacks**
- Number of spades = 13 (one suit)
- Number of Jacks = 4 (one in each suit)
5. **Step 3: Avoid double counting the Jack of spades**
The Jack of spades is counted in both groups, so subtract 1 to avoid double counting.
6. **Step 4: Calculate number of cards that are spades or Jacks**
$$13 + 4 - 1 = 16$$
7. **Step 5: Calculate number of cards that are neither spades nor Jacks**
$$52 - 16 = 36$$
8. **Step 6: Calculate the probability**
$$\frac{36}{52} = \frac{9}{13}$$
**Final answer:** The probability that the card is neither a spade nor a Jack is **$\frac{9}{13}$**.
