Question

Two different numbers are randomly selected from the set {-2, -1, 0, 3, 4, 5} and multiple together. What is the probability that the product is 0?

Answer 1

Explanation:

For the product to be zero one of the picks needs to be zero. It is easier to find the probability of NOT selecting a zero and subtract that from one.

P(0)=1-P(!0)

P(0)=1-(5/6)(4/5)

P(0)=1-4/6

P(0)=(6-4)/6

P(0)=1/3
