Two Holes in One a month apart, same hole, same course

understandinguncertainty.org was produced by the Winton programme for the public understanding of risk based in the Statistical Laboratory in the University of Cambridge. The aim was to help improve the way that uncertainty and risk are discussed in society, and show how probability and statistics can be both useful and entertaining.

Last summer, playing golf with three friends on a course several miles away, my game was of normal average quality (I am a 80-year old amateur who has only played since retirement). At tee no. 8 (130 yard hole) I took a 5 iron and made a better than average drive. To general amazement the ball reached the green and disappeared down the hole. The first hole in one that I have ever achieved! Exactly one month later, the same four people discussed where to play and decided on the same course. There was a lot of ribbing of me at hole 8, along the lines of - well, come on let's see you do a repeat; not a chance, presumably. So, with low expectations I take the same number 5 club and tee off. Again we see the ball climb up the slight rise onto the green - and again the ball disappears. When we get to the green, there is the ball in the hole! What are the odds on this?
