What are the Odds of catching a hockey puck?

I've been to two Sharks games in my life. I set upper level the first game, and 3 rows from the glass the second. I got a game puck the second game I went to when the puck hit the glass and flew over the top. So the odds of getting a puck are 50% I'd have to say. Ha ha ha.
