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 *
