Enigmarch, Day 28: COIN

[tahnan]

I kind of wanted to write a puzzle about what the NPL calls "False Derivatives", e.g. COINCIDE is clearly the crime of killing currency. But I didn't. I did learn about chi-square tests and Fisher's exact test, and I am not including those numbers because I probably did it wrong.

It's not great. It's not terribly original. But it's done.

Coin Flip

I flipped a whole lot of coins to write this puzzle. (Lines ordered roughly by most to least likely. Number of flips not strictly relevant, but provided in case it's helpful. Also, line breaks are not meaningful; there's a soft-hyphen break every five flips, just to keep things from running off the page.)

Heads, check your answer here. Tails, check your answer...there, it's the same either way.
