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.
+68 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
