i am reading a book that explains the mathematics behind coincidences experienced in our daily lives. In one example, the author derives that posits the chance that you will at least once experience one of a set of 100 rare events (each with a one-in-million chance of occurring on any day) in a period of 20 years is as high as 52%. I understand this part completely.
what stumps me is the author’s following comment: It means that for every 20 people you know, there is a greater than 50% chance that one of them will have an amazing story to tell during the course of a year.
my questions are:
1. Is the author using the 1 of 20 phrase to indicate a 95% confidence interval (19 out of 20 times)?
2. How the author expects one of a group of 20 to experience a coincidence in a year’s time? do you mean "within a/the year"?
thanks,
mg
