    your diagram would look like this: first roll --> second roll --> (+ or -) --> + --> + + --> - --> - --> + --> - - --> - --> + so you have a 50% chance of getting a negative number

    The answer is (1/6) * (3/6) = 1/12

    I'm not sure why the 1/6 is there in their answer. Since the question only asks if the product will be positive or negative only the signs on the numbers count.
