Answer #1

1 $20! = 77520 20C7 = 71 × 131$ ways .

2 No of ways = $13! 13 1716$

3 no of ways = $14! 14 5 = 5! x9 2002$

4. 8 letter can be chosen in ¹⁴C₈ = 3003 ways . Now this letter s can be arranged in 8! different ways.

So, total number of ways = $14 Ps- 14cs × 8!- P 121080960 8 = 61$

5. Numnber of ways = 13 ASCO-9.6057 × 1011
