Jasa Rahila babar keh rahe ha 1st Question wasa he solve karna h

i) The order is important so use Permutation

15P3=2730

i) The order is not important so use Combination

15C3=455

Plz send someone solution

order important hai iss liye  15 p3 karna hia

jiss ka farmula hai

npk = n! /(n-k)!

15P3 = 15! /(15-3)!

= 15.14.13 = 2730

selection of three student committe

nCr = n! / n!(n-r)!

= 455
