Solution:
Number of people in the audience = 250
Number of Volunteers to be chosen from 250 volunteers = 2
As this can be done by choosing 2 people out of 250 peoples , the order is not important.
So , we will use combinatorics for this method, because order does not matter here.
So Possible combination= [tex]_{2}^{250}\textrm{C}[/tex]
= [tex]\frac{250!}{248!\times 2!}=249 \times 125[/tex]
= 31125 ways
