A = {0, 1, -3, 6, -8, 20, 4}
B = {-1, 2, -4, 7, 5}
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 option.
A) 1/4 B) 1/3 C) 2/5 D) 4/9 E) 12/35
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) = 4/7*3/5 = 12/35;   P(negative, negative) = 2/7*2/5 = 4/35.   P = 12/35 + 4/35   = 12/35   Answer: 12/35
