Do you have a video on conditional expectations? BTW thank you so much for this resource it is very helpful!

@pedersande Thanks for the comment. I allude to how to compute conditional expectations when I give the video on the law of iterated expectations (E1.7), but I don't formally define conditional expectation on its own. Here's what I would recommend:

Watch the video on joint, marginal and conditional distributions (to learn what a conditional distn is).

Watch the iterated expectations video. Basically, once you have a conditional pdf or pmf, you use that in place of the marginal pdf/pmf.
