The correct expression to determine the number of ways to select a group of 12 records out of 34 is given by the combination formula, which is $\frac { 34 ! } { 22 ! \cdot 12 ! }$. This accounts for the fact that the order in which the records are selected does not matter.

Solve the Problem 34!22!\frac { 34 ! } { 22 ! }22!34!​
