A = {10, 1, -3, 6, -8,-5}
B = {-1, 2, -4, 7}
If a is a number that is randomly selected from Set A, and b is a number that is randomly selected from Set B, what is the probability that ab > 0?	Choose the correct choice from the following:
A) 1/4  B) 1/3  C) 2/5  D) 4/9  E) 1/2
For the product of 2 numbers to be positive either both of them must be positive or both of them must be negative:   P(positive, positive) = 3/6 *2/4 = 6/24;   P(negative, negative) = 3/6*2/4 = 6/24.   P = 6/24 + 6/24   = 12/24   = 1/2   Answer: 1/2
