Futuristic hates studying for the GMAT. He has decided to study 6 hours in 4 days. In his spare time, he will borrow Prat's new Apple computer and play games on it. If he can study for 0,1 or 2 hours on a given day, what is the probability that he will not study at all on a given day? (Assume that all study time distributions have equal prob)

A. 3/10
B 4/10
C 5/10
D 6/10
E 7/10

Prob of studying on day1, day 2 or day3 = 1/3

But prob of studying on day 4 is complex and I am just guessing how to calculate. But will give a shot.

There are 27 total combinations possible for first 3 days.

Out of these
in case of 2,2,2 - 4th day must be 0
in case of 1,2,2 (total 3 cases) - 4th day can be 0,1
in all other 23 cases - 4th day cane be 0,1,2

Now I am stuck!!!!!! :roll:
