If the annual probability for some event is 1%, then the cumulative probability that this event happens within 100 years is 63%. Posted on 2022/03/15 by Carl Robitaille It's not very intuitive how large the cumulative probability of an event is for which the annual probability is low. So I made this chart.If the annual probability for some event is 1%, then the cumulative probability that this event happens within 100 years is 63%. pic.twitter.com/DIxyurBzpo— Max Roser (@MaxCRoser) March 4, 2022
