Birthday paradox explaination
WebExplanation of the Birthday Paradox In a group of 23 people, we will have 253 pairs to look at. A pair is a matching of two people in the room. Each pair will be checked individually to see if they have matching birthdays. The first person has 22 comparisons to make, as they cannot be compared with themselves. WebThen what the Birthday Paradox says is that we need roughly 1.2 times the square root of 365. Which i believe is something like 23, which says we need roughly 23 people in a room, and then with probability one half, two of them will actually have the same birth date. The reason it is called a paradox is because the number 23 seems really small ...
