Conditional probability
... The notion of conditional probabilities has often been misinterpreted. In courts of law, given some testimony, the jury or the judge has to decide on the probability the accused is guilty or not guilty. Let G denotes the guilt of the accused—G = 0 means the accused is not guilty while G = 1 means th ...

... Suppose that a coin has probability p, with 0≤p≤1, of coming up heads on a single flip. Suppose that we flip the coin n times, what can we say about the fraction of heads observed in the n flips? For example, if p=0.5, we draw different numbers of trials in a simulation, the result is given in the t ...

Equational reasoning for conditioning as disintegration
... Conditional distributions are widely used for practical inference, even when the condition has zero probability (such as setting a continuous variable to an observed value). This popularity contrasts with the scary pitfalls (such as Borel’s paradox) that beset rigorous treatments of conditioning. In ...

Note: We divide by n instead of n-1 and use the symbol x instead of sx since we are not calculating the standard deviation of a sample. There is no uncertainty about the values in the distribution or their ...
