Webbprobability to not have the same birthday as you is 364=365: Birthdays occur independently of each other, hence the probability factorises which yields P(Ac) = 364 365 26 and therefore P(A) = 1 364 365 26 = 1 0:931154 = 0:068846: So, the probability that at least one of your classmates has the same birthday as you is about 6:9%: Part (2): WebbThe birthday paradox is that a very small number of people, 23, suffices to have a 50--50 chance that two or more of them have the same birthday. This function generalises the calculation to probabilities other than 0.5, numbers of coincident events other than 2, and numbers of classes other than 365.

WebbA group of 23 people has a probability of approximately 0.5 or 50% (1 chance out of 2) that two people have a common birth date (day + month). P (N = 23)= 1−(364 365)×(363 … WebbWell, it follows through the combination of pairs, i.e the number of pairs of 2 people formed out of 23 people = (23*22)/2 = 253. So the probability of at least one pair matching … extended forecast ft myers beach fl
