₂₁C₉ = 293930

Step-by-step explanation:

9 members out of 21 senators will be selected on the subcommittee on Economy Policy

So we are in case of combinations of 21 people in groups of 9

₂₁C₉ =21! /( (21-9)!) *9! ⇒21*20*19*18*17*16+15*14*13*12! /(21-9)! *9!

 =21*20*19*18*17*16*15*14*13/ 9! ⇒    = 19*2*17*15*14*13/6 ⇒ =293930
