My youngest brother and I have birthdays with a difference of 18 months and 14 days. While that’s not a mathematical marvel in any way it’s been interesting in finding pairs of famous people that either share exactly or are close to our birthdays.<\/p>\n\n\n\n
The birthday problem<\/a> asks for the probability that, in a set of n randomly chosen people, at least two will share a birthday. The birthday paradox refers to the counterintuitive fact that only 23 people are needed for that probability to exceed 50%. This isn’t representative of anyone having my exact birthday which is 1 in 365, but also my brothers birthday which is also 1 in 365. Combining those odds (1 in 133,225) and finding a pair of people considered famous or well-known in some way makes the odds out of this world.<\/p>\n\n\n\n Except the odds seem to favor our pairing, and thus the following…<\/p>\n\n\n\n\n\n\n\n With my birthday being October 14 and my brothers being April 28 there has been one pair that we’ve known for decades and that match us exactly: Joseph Utsler (Oct 14)<\/a> and Joseph Bruce (April 28)<\/a>.<\/p>\n\n\n\n Since this is a rare scenario it’s quite hard to find another pair of famous\/well-known people that exactly match. In finding more there has to be some chronological wiggle room. Thus, a famous pair that allows a 10 day leeway would be Jeannette Charles (Oct 15)<\/a> and Elizabeth Alexandra Mary (April 21)<\/a>.<\/p>\n\n\n\n A third set hasn’t really been found as of this writing but I feel the odds should be in our favor if two are already easily found.<\/p>\n","protected":false},"excerpt":{"rendered":" My youngest brother and I have birthdays with a difference of 18 months and 14 days.
