The plane through non-collinear points A, B and C has vector equation r = a + λ(b − a) + μ(c − a) = (1 − λ − μ)a + λb + μc. The plane through the point with position vector a and parallel to b and c has equation r = a + sb + tc. The perpendicular ...

1.1 The Mean, Median and Mode. When given a set of raw data one of the most useful ways of summarising that data is to find an average of that set of data. An average is a measure of the centre of the data set. There are three common ways of describing the centre of a set of numbers.
A very important formula involving conditional probabilities is the Bayes rule. This is arguably the most important formula in all of probability and statistics. At a high level, the Bayes rule tells us how to compute P(BjA) in terms of P(AjB) and other terms. Note that these two conditional probabilities)
