The six faces of a dice are numbered -3, -2, -1, 0, 1 and 2. If the dice is rolled twice and the two numbers are multiplied together, what is the probability that the result is a negative?

use the possibility diagram

OpenStudy (anonymous):

I dont know what that is :/

OpenStudy (anonymous):

no other option..learn the possiblity diagram tree!!

OpenStudy (anonymous):

no need for tree possibility diagram is enough

OpenStudy (anonymous):

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

@8124242246; your answer is different to sallysim's

OpenStudy (anonymous):

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.
