IIT JEE Probability - Important Formulas

To determine the combined probability of events occurring with replacement, we simply multiply the probabilities of the events directly. The formula for such cases is as follows: P(A and B) = P(A) $\times$ P(B)


  1. Conditional probability pertains to the likelihood of one event occurring after another has already taken place. The formula for conditional probability is expressed as: P(A and B) = P(A) $\times$ P(B|A)

  2. Rules of Addition When considering two events, A and B, with their respective probabilities denoted as P(A) and P(B), the rules of addition can be summarized as follows:


Rule 1 (Mutually Exclusive Events): The probability of either event A or event B occurring is the sum of their individual probabilities: P(A or B) = P(A) + P(B)


These formulas and rules are fundamental for probability calculations in various scenarios.
