      With a group of just 25 people, the probability of sharing a birthday is already over 50%.

      This phenomenon occurs because there are only 365 possible birthdays in a year (ignoring February 29th for simplicity). As the group size grows, the number of possible birthday combinations increases exponentially, making it more likely that two people will share the same birthday.

    • In a research study or survey, the birthday paradox can affect the accuracy of data collection and analysis.
    • The birthday paradox is a mathematical concept that was first introduced in the 1930s. It states that in a group of randomly selected people, there is a greater than 50% chance that at least two people share the same birthday. This may seem counterintuitive, as we tend to think that birthdays are unique and random events.
