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 ...

Venn diagrams can be useful for organising information about frequencies and probabilities, which can then be used to solve conditional probability problems. 90 pupils were asked whether they owned a ...

90 pupils were asked whether they owned a laptop or a tablet device. 52 said they owned a laptop. 45 said they owned a tablet. 23 said they owned both. Find the probability that a pupil chosen at ...

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 ...

Possibility theory and conditional probability offer complementary perspectives for modelling uncertainty, with each framework contributing distinct advantages. Possibility theory, rooted in fuzzy set ...

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.
