Probability of a given arrangement | Probability | Grade 11 | Math | Khan Academy

Описание: In this video, we calculate probabilities related to the random arrangement of a sequence of events, using the example of Riya visiting four cities (A, B, C, D) in a random order. We'll determine the probability of specific orderings, such as A being visited before B, A before B and B before C, A being visited first and B last, A being visited either first or second, and A being visited just before B.
