there are 3 Glubnorians in the room. (They're big, so the room is getting crowded.) What's the probability that at least two of them have the same birthday?

    probability that there's a shared birthday is 365/3652 or about o. 27%

    Explanation:

    Probability is how probable is for a determinate event to happens, when we are not sure of the result of certain event we can talk of the probability. The best example of probability is flipping a coin there is two possible probabilities you can get tails or you can get heads. What is the probability of getting heads? We can find it using the equation

    (p) a = ? And you might thing intuitively that there is 50% of probability in this case

    (p) a = 1/2 = 50%

    in can be expressed

    P = Likely / posibble

    so if we got p3

    we need to take for each person the day that is not likely to share with the others from 1

    p3 = 1 - 364 365 • 363 365 = 1 - 364 • 363 3652,
