When a pair of dice is thrown the set of possible outcomes are...................... {11,12,13,14,15,16,21,22,23,24,25,26,31,32,33,34,35,36,41,42,43,44,45,46,51,52,53,54,55,56,62,62,63,64,65,66}
So n(S) = 36. Let A be the event of getting a sum which is a perfect cube and divisible by 3.
Then A = { }. So n(A) = 0
So. P(A) = n(A)/n(S)
= 0/36 = 0
