C(7,3)*C(8,3)
Having a bit of trouble here:
There are 7 seals and 8 dolphins entered in an aquatic obedience show. How many ways could you select a final group to judge if it must consist of 3 seals and 3 dolphins? How many ways could you award first, second and third place winners?
I am not sure if you have to subtract three from each one on the first question or what? Really stuck.
