Bayesian statistics lets people to combine their prior knowledges with observations to disagree or update with their beliefs in a quantitative way.

Binomial Distribution describes probabilities of getting a number of successful trials (variable, k) within a fixed total number of trials (constant parameter, n), given the probability of one successful trial is known and fixed (constant parameter, p) (B(k; n, p)). Each trial in binomial distribution, as described above, is a Bernoulli event that can onlyContinue reading “Binomial Distribution”

Probability captures how strong, or how uncertain, we believe in the world. It is a natural extension of logic (absolute believes, binaries). The probability for an event to occur lies between 0 and 1 (rule No.1). Probability can be calculated as the proportion of number of desirable events over the total number of events.
