Best ResponseYou've already chosen the best response.1i try these problems by taking small numbers first let there be just 2 people in that room then the probability "that two or more people share the same birthday" will be 1 probability that BOTH will not have same birthday (assuming 366 days a year) so, \(\large 1 \dfrac{366}{366}\times \dfrac{365}{366}\) now extending this for 'n' people \(\large 0.99 =1 \dfrac{\dfrac{366!}{(366n)!}}{366^n}\) am i on right path ? (wondering how the hell can i solve that for n :O O.o)
