SUMMARY
The probability of three randomly selected individuals sharing the same birthday is calculated as (365/365)(1/365)(1/365), resulting in a probability of 0.00000751. Conversely, the probability that none of the three individuals share a birthday is calculated as (365/365)(364/365)(363/365), yielding a probability of 0.992. A direct counting approach is recommended for a clearer understanding, involving the calculation of total birthday possibilities and the respective counts for both scenarios.
