Two distinct positive integers from 1 to 50 inclusive are chosen.  Let the sum of the integers equal $S$ and the product equal $P$.  What is the probability that $P+S$ is one less than a multiple of 5?The answer is in the form rac{m}{n}, where gcd(m, n) = 1. Please provide the value of m + n.

Let's think step by step and output the final answer within \boxed{}.
