Puzzle from India

I was enroute from India to USA when I got a call from one of my nephews with the following math problem he was stuck with. I am posting that as the puzzle of this week.

There is a jar with 50 pieces of paper written “1” thru “50” in them. You pick 5 of them at random and lay them out in increasing sequence. What is the probability that the middle number is 30?
