Guess, what does this graph show?

How many liters of beer you drink per hour.

Such function would be concave, I think.

Maybe something like amount of people who’ve already met their last husband/wife (by the age).

Funny, but no :)

Dan Mysak said...

Well, what _does_ it show? :-)

Roman Cheplyaka said...

Okay, it shows some probability depending on some number.
Any ideas now?
(You can ask me in private if you really want to know, but I'm not going to post an answer here myself until someone guesses :)

It shows probability for set of n people to be a pair of people in it who have a same date of birth.

Interestingly, that idea came up during the first 10 minutes of thinking, but I’ve rejected it by some reason.

Bravo!

Quite an interesting puzzle :-)
