Answer:
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
