With two people in the room, the probability that the second person shares a birthday with the first is 1/365 (let's ignore leap years for the time being). Thus, the probability that they DON'T share a birthday is 364/365.

Add a third person. The probability that this person does not share a birthday with either of the first two (assuming they don't share a birthday) is 363/365. Thus, the probability that none of the three share a birthday is (364/365)*(363/365).

The probability that a fourth person doesn't share a birthday with any of the first three is 362/365. Thus the probability that none of the four share a birthday is (364/365)*(363/365)*(362/365).

See the pattern here? The probability of the n-th person not sharing a birthday is (366-n)/365. Keep adding people and multiplying the terms together until the probability of no one sharing a birthday drops below 0.5 --- which is when the probability of at least one pair sharing a birthday climbs above 50%.

Since this sounds like a homework problem, you'll have to do the rest.

I tjust tried the link above and it didn't work this way.

First, you enter this : http://www.sagem.com/support/site/sagem_carte.php

Second select your country,

Third, below "Sheetfed Philips"select the model,

A new page is opened and let you select "User manuals" on the left,

In english, it takes 4.9Mo in pdf format.

I hope this helps you
