The coach has to select 2 co-

captains from the 15 girls out for

soccer. How many selections are

possible?

105 selection s

Step-by-step explanation:

Given:

The coach has to select 2 co-captains from the 15 girls out for soccer

n = 15

r = 2

The number of selections possible is;

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

Since no other is specified.

Substituting the values of n and r;

N = 15C2 = 15!/2! (15-2) !

N = (15*14) / 2

N = 105

Therefore, she have 105 possible selections
