##### Probability and the Birthday problem Part-II
« on: June 02, 2012, 07:15:03 PM »
In my previous post Probability and the Birthday problem Part-I I asked-
What is the probability (or chance) that I share my birthday with any two or more of my students (in a section)?
The answer is given in this part.

In the following table I present the chances (in percentage) of sharing my birthday.

Excellent mathematics! We all have a probability to sheer the birth day!

One more thing You can do ... You can find out the probability of  birthday for our faculty members in different months and then we can easily know how many times we will receive party in a month or year!

Thanks

Dear Sir you will enjoy the third part of this topic as you enjoyed the first and second parts. You remind me a very good thing. You can also calculate the chances of sharing birthday of our faculty members.

Very interesting and also confusing to us to guess the real probability. However I request you to calculate the probability to return of Elius Ali.
