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.

= 
= 31125 ways
The answer is 125. If you were to pair 250 people in 2, that would be 250 divided by 2. And 250 divided by 2 is 125.
