Show the odds of any two individuals having the same birthday are slightly greater than 1:1 (1:.9732 actually). Assume there are 23 individuals in the room and 365 days in a year ignoring leap year.
To calculate the probability of finding two people with the same birthday in the group of 23 people, we, instead, calculate
the probability that NO TWO people will share a birthday; that is, they will ...
Neat and step-by-step approach and solution is presented to the birthday paradox.
