When every outcome in a situation is equally likely, each single outcome has probability 1/n, where n is the total number of outcomes. The probability of an event A is then counted, not chosen: P(A) = number of favourable outcomes ÷ total number of outcomes. Because the favourable outcomes are some of the total, the answer always sits between 0 (nothing favourable) and 1 (everything favourable), and the outcomes outside A fill the rest, so P(not A) = 1 − P(A). This is the real knowscape from knowhere, not a picture of one. Drag it. Watch what actually changes.
A scatterplot shows you two things moving together, and correlation puts a number on how tightly. But together isn't because — the line you draw predicts, it doesn't explain. Every question here is really asking: how strong is the pattern, and how far can you trust it?
A row of n equal outcome cells with k of them lit as the event A, above a 0-to-1 line split into P(A) and P(not A); the overlay reads P(A) = k/n as a fraction and a decimal, and the two colours always fill the whole line.
knowhere maps every concept to what it rests on and what rests on it — 2 underneath this one, 4 built on top. Each one says why, in a sentence, not as an arrow on a diagram.
Each one is its own knowscape in the app — built for how a particular student takes things in, not one explanation handed to everybody.
Every HSC and VCE concept in knowhere is built like this one — mapped to your curriculum, never capped by it. Free for a week. No lock-in, cancel inside the week and pay nothing.
Free for a week, then one payment. It ends itself after the last exam — no subscription.
Free for a week, then a plan you can stop any time.
