The Birthday Problem Probability. It is easier to do the complement the probability of having different birthdays among the group of people. Is this really true. The birthday problem also called the birthday paradox deals with the probability that in a set of n n n randomly selected people at least two people share the same birthday. Created by Sal Khan.
Created by Sal Khan. The solution is 1-Ptexteverybody has a different birthday. Calculate the probability of shares falling or rising in value. It is easier to do the complement the probability of having different birthdays among the group of people. Whilst many aspects of probability seem relatively intuitive it often produces some rather unexpected yet remarkable results as will be demonstrated by the birthday problem below. Is this really true.
We call this probability.
If one assumes for simplicity that a year contains 365 days and that each day is equally likely to be the birthday of a randomly selected person then in a group of n people there are 365 n possible combinations of birthdays. Is this really true. Whilst many aspects of probability seem relatively intuitive it often produces some rather unexpected yet remarkable results as will be demonstrated by the birthday problem below. How many do you need in a room to have an evens or higher chance that 2 or more share a birthday. The probability that at least 2 people in a room of 30 share the same birthday. Though it is not technically a paradox it is often referred to as such because the probability is counter-intuitively high.
