When two dies are rolled, there are 36 different outcomes. (1,1),(1,2),....(6,6).
Let A denote the event of rolling doubles.
There are 6 doubles (1,1),(2,2),(3,3),(4,4),(5,5),(6,6)
P(A) = 6/36=1/6
Let B denote the event that the product is 18.
Count how many of these outcomes give you a product of 18. Only (3,6) and (6,3) give you a product of 18.
P(B)=2/36=1/18
There are no events that give you a double and whose product is 18.
P(A or B) = P(A)+P(B)
P( double or 18) = 1/6+1/18 = 4/18 = 2/9
