Probability and the Birthday problem Part-III

[Mohammad Hassan Murad]

INTERESTING FACTS
We note that the same phenomenon pertains to deaths, for example, the probability that at least two former presidents of the United States share a birth month and day and the probability that at least two former presidents share a death day and month is the same. From the table (See Probability and the Birthday problem Part-I) for n = 44 presidents, the probability is 0.9328. Which shows that, there is about 93.28% chance that the former any two or more US Presidents share their birthday or death day.

James Polk (11th US President)

Warren G Harding (29th US President)

Millard Fillmore (13th US President)

William Howard Taft (27th US President)

John Adams (2nd US President)

Thomas Jefferson (3rd US President)

James Monroe (5th US President)

James Polk and Warren Harding were born on November 2; Milliard Fillmore and William Howard Taft died on March 8. John Adams, Thomas Jefferson, and James Monroe all died on July 4 (Independence Day). Of course, these presidents’ birth and death events do not prove the phenomenon.
