… and by basic, I mean basic. I sometimes find people come to me with questions and no one has ever taken the time to give them the most basic underpinnings in probability that would make their lives a lot easier. A friend of mine is having this problem and is on a limited time frame for solving it, so this is quick and dirty and contains both wild ad-lib on my part and swearing. When I get some more time, I’ll try and expand and improve, but for now it’s better than nothing.
Youtube explainer: done without microphone, sorry- time limit again.
I mentioned two links in the screencast. One was Allen Downey’s walkthrough with python, you don’t need to know anything about Python to explore this one: well worth it. The other is Victor Powell’s visualisation of conditional probability. Again, worth a few minutes exploration.
Good luck! Hit me up in the comments section if you’ve got any questions, this was a super quick run through so it’s a summary at best.
