what is the probability of always having x + y > 0 , where y < 0
"total value of x can be : 1 . x < 0 ; 2 . x = 0 ; 3 . x > 0 but less than y in magnitude 4 . x > 0 as well as | y | so probability of having x + y > 0 would be 1 / 4 answer : d"
divide(const_2, choose(add(const_3, const_3), const_3))
