Math test

I decided to finally implement some math support. Here’s a test post.

an+bn=cn

v(t)=at1+(atc)2

I hope equation support will come in handy.

Hats

Here’s a fun math problem…

Suppose there are n people. Each person has a hat.

Now, you collect all the hats, and distribute them back randomly. There is a certain probability that no one will get their own back.

What is the limit of this probability as n approaches infinity?

Hint: It’s a probability, so it’ll be in the [0,1] range.

(I’ll post a solution in a few days.)

Monty Hall

Last night I stumbled across the Wikipedia article: Monty Hall problem. At first it seems completely counter-intuitive, but when you think about it, the host reveals information about your choice by purposefully opening a door with a goat.
