Nigel Case · Answer 1

The number of ways in this case will involve computation of number of combinations available. That is,

Number of ways to select 5 = Total number C Number to be chosen. Where "C" stands for combination

Substituting;

Number of ways to select 5 from 10 people = 10C5 = 10!/{5! * (10-5) !} = 10! / (5!*5!) = 252 ways
