“actualllllyyyyy” he’s saying something different. If you take a 0.3% chance for N days where N is large, you’ll land it 0.003N times, or once every ~333 days. The chance of landing it within any particular window of K days is a different c

Depends on your field. If you're studying mathematics or computer science, learning happens mostly through deep work in isolation and there's enough material out there (books, papers, etc.) to support more than a lifetime of probl

It's not that simple because taxes modify gains but not losses. Imagine we bet $1 on a coin toss. The expected value for either of us is $0. Now imagine the winner is required to pay 10% tax on his proceeds. The expected value becomes

You might be more comfortable with Python syntax than with standard mathematical syntax, but I wouldn't think of it as being closer to "just a logical description" or closer to being the "raw idea." You're just

I’m all for frugality. But you wouldn’t pay $2 for the freedom to use those 45 minutes in some other way?
