We have to determine the how many different councils consisting of 5 freshmen and 7 sophomores are possible
[tex]_n C_r=\frac{n !}{r ! (n-r) !}_n C_r = number of combinations\\\n = total number of objects in the set\\\r = number of choosing objects from the set[/tex]
The total number of the council is
[tex]_{10} C_5\times _9 C_7[/tex]
=252(36)
