Independent events. Multiplication of probabilities

Independence
Events AA and BB are called independent if the occurrence of one does not change the probability of the other: P(AB)=P(A)P(B)P(A\cap B)=P(A)\cdot P(B) (in the standard setup this is taken as the definition of independence in problems). Examples of “back-to-back” trials with replacement and fair shuffling are often modeled as independent steps.
