Question
how many ways can a high school basketball coach find the 5 players for her starting lineup from 14 players?
Step1: Identify the combination formula
The formula for combinations is \(C(n,r)=\frac{n!}{r!(n - r)!}\), where \(n = 14\) (total number of players) and \(r=5\) (number of players to choose).
Step2: Calculate factorial values
\(n!=14! = 14\times13\times12\times11\times10\times9!\)
\(r!=5! = 5\times4\times3\times2\times1\)
\((n - r)!=(14 - 5)!=9!\)
Step3: Substitute into the formula
