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 23 chance of being negative.
Thus, the probability is 1×23=23
