Probability

I am teaching probability in my math class right now.

The probability of ___________ increases when _______________ happens.

So...we are having a conversation about the words certain and impossible. Here is how it went.

Me: There are some things that are certain and some things that are impossible. For example it is certain that tomorrow will be Wednesday and impossible that tomorrow will be Friday.

Student #1: But....but..what if aliens came to Earth and took over our land and made it alien world and change tomorrow to Friday.

Student #2: Well then we would all be screwed and not need probability anyway.

Student #1: Yeah and we wouldn't have homework

Me: You would still have homework.
