- 0dd num on die=1,3,5
even num on die=2,4,6
possibilities of a,b,c=(e,e,e),(o,o,o),(o,e,e),(e,o,e) [a.b+c=even]
=4*(3*3*3) [ num of even=3,num of 0dd=3]

- Ans : 28 / 36
there is four cases :
a.b+c
probability of even=1/6,odd=1/6
even.odd+even
odd.even+even
even.even+even
odd.odd+odd
4*{(1/6*1/6)+1/6}=28/36
