## Exercise 7.2 Class 11 maths 7. Permutations and Combinations - ncert solutions - Toppers Study

## Exercise 7.2

**Q1. Evaluate:** **(i) 8!**

**Solution: **

(i) 8! = 1 × 2 × 3 × 4 × 5 × 6 × 7 × 8 = 40320

**(ii) 4! - 3! **

**Solution: **

(ii) 4! = 1 × 2 × 3 × 4 = 24

3! = 1 × 2 × 3 = 6

∴ 4! – 3! = 24 – 6 = 18

**Q2. Is 3! + 4! = 7!? **

**Solution:** 3! = 1 × 2 × 3 = 6

4! = 1 × 2 × 3 × 4 = 24

3! + 4! = 6 + 24 = 30

7! = 1 × 2 × 3 × 4 × 5 × 6 × 7 = 5040

∴ 3! + 4! ≠ 7!
