@gregeganSF@mathstodon.xyz This is such a trap for nerds! My wife and all the math people I shared it with are thoroughly captivated by the puzzles! We're stumped on the jellybean question. When do we need 4 samples? It looks like if you get red or blue first, you can figure out the order from one more sample. (2 total) If you get green, you look at the next chute, which will never be green. And then you're back to the previous case. (1+2 total) I even wrote some code to check.
