Answer:
2496144
Explanation:
Total number of members of the senate on the finance committee (n)= 24
Number of members in each subcommittee(r) = 13
We need to make use of the combinations formula
C(n,r) =

1) Plugging in the values of n and r into formula, we get
C(24,13) =

=

=

2) Cancelling out the 13! from the top and bottom, we get
=

=

3) Upon simplifying the numbers on the top and bottom, we get
C(24,13) = 2496144
