WebbP ( A AND B) = P ( A) P ( B) Two events A and B are independent events if the knowledge that one occurred does not affect the chance the other occurs. For example, the outcomes of two roles of a fair die are independent events. The outcome of the first roll does not change the probability for the outcome of the second roll. WebbEvents A and B are called mutually exclusive if they cannot both occur, that is, P (A and B) = 0. In this situation, P (A or B) = P (A) + P (B). Events A and B are called independent if the …

WebbThe probability tells you, since this is an independent event, the next time you flip a coin, it will still be 50% that you will get heads and 50% that you will get tails. If, however, you consider it as a compound event, there's 1/ (2^6), about 1.5% that … WebbLearn about the independent events in probability, also how is it different from the mutually exclusive events. Master the probability concepts for IIT JEE exams. ... The occurrence of one event results in the non-occurrence of the other event.
