Answer 1

14. Number of permutations, nPr = n!/(n-r)!

Number of combinations, nCr = n!/(r! x (n-r)!)

The number of times the permutaion is larger = 4!

= 24

15. Number of ways 8 people can be lined up = 8!

16. Number of different systems = 4x3x2x2

17. Number of ways to select 3 flavors of ice cream from 15 = 15C3

= 15!/3!12!
