Editing Four-leaf clover (section)

==Occurrence==
A 2017 survey of approximately 5.7 million clovers in six European countries found the frequency of 4-leaf clovers to be around 5000 to 1 (one 4-leaf clover for every 5076 normal 3-leaf clovers), almost twice the commonly stated probability of 10,000 to 1. According to this survey, the frequency of a 5-leaf clover is 24,390 to 1, and that of a 6-leaf clover is 312,500 to 1.<ref name="auto">{{cite web |last1=Sperling |first1=Uli |title=How rare are 4-leaf clovers really? |url=https://www.sharetheluck.ch/single-post/How-rare-are-four-leaf-clovers-really |website=Share the luck |archive-url=https://web.archive.org/web/20220616134250/https://www.sharetheluck.ch/single-post/How-rare-are-four-leaf-clovers-really |archive-date=16 June 2022 |date=24 July 2017}}</ref>
