In committees the order doesn't matter, i.e. AB is the same as BA. So we are dealing with combinations in this problem. We have to find the size of the committee formed by the boys and girls separately, and then multiply these together to find our answer.

For the boys:

$C(8,3) = 56$

and for the girls:

$C(7,2) = 21$

therefore,

$C(8,3) \cdot C(7,2) = 56 \cdot 21 = 1176$ committees are possible.
