Webb30 okt. 2024 · Probability of a match + probability of no match is equal to 1. So we can work it out like this: First we assume that a first person with a birthday exists. The probability of this person 1 having a birthday is \( \frac{365}{365} \). Then we multiply that number by the probability that person 2 doesn't share the same birthday: \( \frac{364}{365 WebbAmong n people, it deals with the probability p of at least 2 people having the same birthday. From the Pigeonhole Principle, we can say that there must be at least 367 people (considering 366 days of a leap year) to ensure a 100% probability that at least two people have the same birthday.

Webb22 sep. 2015 · I'm trying to create a program that finds the probability of two random students in a room to have the same birthday. Number of students and number of simulations is inputted. Whenever I run it though, with 23 students, I consistently get 0.69, which is inconsistent with the actual answer of about 0.50. Webb1 aug. 2024 · Thus the minimum of the probability of getting two random birthdays the same is achieved when all $p_k$ are equal, namely $p_k = 1/n$, and if they are not all … hazenchamber westriv.com
