Agreed. I was very excited when I received the writeup, and we prepared the rent posts on expected value and variance to get students used to these probability concepts, before blowing your mind with Bayes' Theorem.

Thanks to Bob for the kudos, and to Calvin for the opportunity! I really enjoyed putting it together.

Mind-blowing indeed.

There's no way to see the solutions to the practice problems, right? Because I'd love to check my answers.

As of right now, no, but I'm sure you're not the only one that would like to check your answers! I'll talk with Calvin to see what the best way to go about that would be. Thanks for the suggestion!

are you people aware that probability type questions can easily be confronted with programing...like for example in Java...the java.util.Random class if coded properly can easily estimate up to a great accuracy the probability of an event

Simulations can be an effective way of estimating probabilities, but that takes all the fun math out of it.
