Answer
The probability of drawing a card ranked 3 through 7 is 5/13 (approximately 38.46%). The probability of drawing a red face card is 3/26 (approximately 11.54%).
Solution
Let's tackle each question one by one based on a standard 52-card deck without Jokers.
---
### **1. Probability of Drawing Cards 3 Through 7**
**Understanding the Problem:**
- **Cards 3 through 7** refer to the ranks **3, 4, 5, 6, and 7** in each of the four suits (Hearts, Diamonds, Clubs, Spades).
- Each rank has **4 cards** (one in each suit).
**Calculating the Probability:**
1. **Total favorable cards:**
- There are **5 ranks** (3, 4, 5, 6, 7).
- Each rank has **4 cards**.
- So, total favorable cards = 5 ranks × 4 suits = **20 cards**.
2. **Total possible cards:**
- A standard deck has **52 cards**.
3. **Probability Formula:**
\[
\text{Probability} = \frac{\text{Number of favorable outcomes}}{\text{Total number of possible outcomes}} = \frac{20}{52}
\]
4. **Simplifying the Fraction:**
\[
\frac{20}{52} = \frac{5}{13} \approx 0.3846 \text{ or } 38.46\%
\]
**Answer:**
The probability of drawing a card ranked 3 through 7 is **\(\frac{5}{13}\) or approximately 38.46%**.

### **2. Probability of Drawing a Red Face Card**
**Understanding the Problem:**
- **Face cards** include **Jacks, Queens, and Kings**.
- There are **4 suits**: Hearts and Diamonds are **red**, while Clubs and Spades are **black**.
- Each suit has **3 face cards** (Jack, Queen, King).
**Calculating the Probability:**
1. **Total face cards:**
- 3 face cards per suit × 4 suits = **12 face cards**.
2. **Total red face cards:**
- Since Hearts and Diamonds are red, and each has 3 face cards:
- 3 face cards per red suit × 2 red suits = **6 red face cards**.
3. **Total possible cards:**
- A standard deck has **52 cards**.
4. **Probability Formula:**
\[
\text{Probability} = \frac{\text{Number of red face cards}}{\text{Total number of possible cards}} = \frac{6}{52}
\]
5. **Simplifying the Fraction:**
\[
\frac{6}{52} = \frac{3}{26} \approx 0.1154 \text{ or } 11.54\%
\]
**Answer:**
The probability of drawing a red face card is **\(\frac{3}{26}\) or approximately 11.54%**.
---
### **Summary**
1. **Probability of drawing a card ranked 3 through 7:** \(\frac{5}{13}\) (~38.46%)
2. **Probability of drawing a red face card:** \(\frac{3}{26}\) (~11.54%)
