I wonder where they are from...
+2668 In that question, the answerer leads to the right answer, but they fail to consider that the numbers chosen don't have to be an integer.
+2668 For the product to be positive, we need both x and y to be negative.
X is gauarnteed to be negative, and Y has a \(2 \over 3\) chance of being negative.
Thus, the probability is \(1 \times {2 \over 3} = \color{brown}\boxed{2 \over 3}\)
