Birthday paradox
http://en.wikipedia.org/wiki/Birthday_paradox
The birthday paradox states that if there are 23 people in a room then there is a slightly more than 50:50 chance that at least two of them will have the same birthday. This means that a higher probability applies to a typical school class size of thirty, where the 'paradox' is often cited. For 60 or more people, the probability is greater than 99%. This is not a paradox in the sense of leading to a logical contradiction; it is a paradox in the sense that it is a mathematical truth that contradicts common intuition. Most people estimate that the chance is much lower than 50:50. Calculating this probability (and related ones) is the birthday problem. The mathematics behind it has been used to devise a well-known cryptographical attack named the birthday attack.
let's start the test here! I experimented it on another forum and it worked, let's see here
