Right away this looks like something related math, what with the [█, █) and ~ ███(*█*).

I'm trying to spend a little less time on these, so let me try a few things right away:

*mathematics* gets 0 but *function* gets 16.

A bunch of other words get me very little (*equation* gets 3, but *linear, cosine, *and *algebra* get 0). Entering *x* to fill blanks all those equations and definitions helps at least confirm I'm on the right track.

But my limited knowledge of mathematics is showing, here, and all my next guesses (*axis, derives, quadratic, square, number, value, *and* sum*) yield very little.

But then I hit on *statistics*, and that seems promising.

I try *ratio* (spelling it correctly for a change, after paying close attention so I don't mistype *radio* again), but that's no good, but then *theory* helps a little (I was thinking *game theory* even though I knew that probably didn't have anything to do with the article) - and that got me to *probability* for the phrase *probability theory* (a logical connection to *statistics* - which doesn't have a lot of hits, but appears in the first sentence).

So now I'm pretty well stumped - I'm on the right track, but I bet I lack the domain knowledge to actually figure this out.

HAH! And once again, I guess a word that I figure will at most give me a few hits, maybe nudge me in the right direction, but turns out to actually be part of the topic: *distribution*.

And once again, I'm not sure I can figure out the missing title word. It's not *random*; too long.

Oh, but it starts with a vowel:

"The probability ███████ function (███) of an ███████████ distribution"

But, after wracking my brain, I concluded that I was not going to be able to solve this one, so I cheated - I went to the list of Level 4 articles, clicked into Math, and searched for Distribution - and seeing one that started with a vowel, I entered *exponential* , and that unlocked it for me.

So, yeah, statistics is something I've tried to dive into many times and never gotten very far. I should learn more about this stuff.

So - on the right track, but ultimately stumped, and had to cheat to get it.

Better luck tomorrow, maybe.
