Two different integers are randomly chosen from the set \{ -5, -8, 7, 4, -2, 3, 1 \}. What is the probability that their product is negative? Express your answer as a common fraction.

Hi Guest,

Sorry for the late response

In this set of number, there are 3 negative numbers:

-5, -8, -2

If any of those number multiply 7, 4, 3, or 1, it will be negative

3 negative * 4 positive = 12 possibilities

Total possibilities = 21

So the probability that their product is negative is **12/21**
