Question

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?

Answer 1

Answer:

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 ,
