1. Become President
Are you interested in holding the highest political office in the country and being one of the most powerful people in the world? Increase your chances drastically by joining the Masonic Brotherhood! Fourteen out of 43 U.S. Presidents have been Freemasons. According to the preliminary calculations of a friend with a degree in mathematics, becoming a Freemason will multiply your chances of being President by four.*
* Using Bayes’ Rule and some healthy speculation:
p(president | mason) = ( p(mason | president)* p(president) ) / p(mason)
= ( (14 / 43) * (43 / 472000000) ) / (1246241 / 317000000)
~ 0.0008% p(president | american) = ( p(american | president) * p(president) ) / p(american)
= ( 1 * (43 / 472000000) ) / (317000000 / 6916000000)
Using 2013 figures for U.S. population, World population, and Freemason membership.
So that being a Freemason makes one roughly four times as likely to be president.
