A six-sided die with sides numbered 1 through 6 is tossed 2 times. What is the probability that the product of the two toss results will be even?

I just wrote out all the possible choices and of the 36 choices, 27 of them had a product that was even. I don't remember the shortcut to this, but I just wrote out 1*1, 1*2, 1*3, etc.
