Answer:
30C6
Step-by-step explanation:
Given, the total number of members in the chorus are 30.
Also, it is given that 6 members from the chorus have to be
chosen for a special performance.
The number of ways of choosing r people out of given n people
is given by the expression
nCr
= n!/r!(n-r)!
So the number of ways of choosing 6 members out of 30 are
30C6
= 30!/24!6!
But since only the expression to represent the number of ways
was asked not the exact number of ways we can leave the
answer as 30C6 .
