You compete (as understood from the article) in Powerball by 50 choose 5, 20 choose 1. So 1 in (50!/(5!⨉45!)⨉20 = 42.375.200. There are 15 ascending "suspicious" winning sequences, as the choice of Powerball is always last and thus must be 6-20. Therefore the chance of winning Powerball with a "suspicious" sequence is 15 in 42.375.200. If there are 1000 Powerballs drawings per day for a year, that gives a chance of approximately 12% of happening at least once a year. https://www.wolframalpha.com/input/?i=binomial+calculator&assumption=%7B%22F%22%2C+%22BinomialProbabilities%22%2C+%22p%22%7D+-%3E%220.00000035398063%22&assumption=%7B%22F%22%2C+%22BinomialProbabilities%22%2C+%22x%22%7D+-%3E%220%22&assumption=%22FSelect%22+-%3E+%7B%7B%22BinomialProbabilities%22%7D%7D&assumption=%7B%22F%22%2C+%22BinomialProbabilities%22%2C+%22n%22%7D+-%3E%22365000%22 https://www.wolframalpha.com/input/?i=binomial+calculator&as...
