P(success) = Probability of getting 2 or 5 is 2/6 = 1/3
P(failure) = Probability of not getting 2 or 5 is 4/6 = 2/3
Probability of 0 success and 3 failure is 
Probability of 1 success and 2 failure is 
Probability of 2 success and 1 failure is   
Probability of 3 success and 0 failure is
x is the number of success and p(x) is probability of x times success.
