State Bayes' theorem.1 / 10

P(H|E) = P(E|H) × P(H) / P(E). Posterior ∝ Likelihood × Prior. P(H): prior belief; P(E|H): likelihood of evidence given hypothesis; P(H|E): posterior belief after observing evidence.

What is a net of a 3D solid?1 / 8

A net is the flat pattern you get when you unfold a 3D solid along its edges so every face lies flat. Adding up the area of every piece in the net gives the solid's total surface area.

What is the difference between a population and a sample?1 / 9

The population is the entire group you want to learn about — every student in a school, every voter in a country. A sample is a smaller subset of the population that is actually measured or surveyed.
