How likely is it that someone will hit a hole in 1 on a par 3 hole?

Dear Srascoff,

American golfers shoot about 300,000 holes-in-one every year.

The odds of shooting a hole-in-one are about 30,000 to 1.


Both of these statements are (roughly) true. The golf industry
estimates that there are 26 million golfers in America and they play
an average of 21 rounds per year. That's 546 million rounds, or 9.8
billion holes. So 300,000 holes-in-one amounts to about one for every
30,000 holes played.
