In this notebook, I will show a trick of using NumPy to solve a classical conditional probability problem of random walks: > Give an standard random walk (start at origin and with the probability of ...

Investopedia contributors come from a range of backgrounds, and over 25 years there have been thousands of expert writers and editors who have contributed. Thomas J Catalano is a CFP and Registered ...

Bank exams typically feature questions on simple probability, conditional probability, combinations and permutations, events (independent and dependent), Bayes’ theorem, and sometimes more complex ...

Bayes’ Rule is a way of calculating conditional probabilities. It is difficult to find an explanation of its relevance that is both mathematically comprehensive and easily accessible to all readers.

We elaborate on an alternative representation of conditional probability to the usual tree diagram. We term the representation “turtleback diagram” for its resemblance to the pattern on turtle shells.
