I guess I have one very basic and fundamental question.

Well... I too on the test had tried in a similar manner, except that I took a + instead of a * inbtween the terms...

(16C4) + (12C4) + (8C4)+ (4C4)

I seem to get confused when we have which sign.. is there some mechanism with which I can be sure of ?

Permutations/Combinations & at times Probability is something which I cannot at times get hold of...

Also Any special tips how I can make my 49 a 51 on G-Day?

Keep it simple
OR means +
AND means *

Here it is AND so *
