Question

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?

Answer 1

When you multiply a negative with a positive, then the result is negative.
So the probability of a negative number when they are multiplied is given by:

P(Negative) * P(Positive)

Answer 2

P(Negative) is 3/6
P(Non-negative) is 3/6

3/6 * 3/6 = 1/2 * 1/2 = 1/4

Answer 3

So that is the final probability.

Answer 4

P(negative no.) = 2* P(negative) *P(positive) :since your are having two dices
P(negative) = 3/6
P(positive) = 2/6
therefore P(negative no.) = 1/3

Answer 5

Oh yes
