We will make use of the concept of conditional probability to find the solution. Explanation: We are going to use the definition of conditional probability for this.
Webp (a ∩ b) = p (a) p (b) p (a ∩ b) = p (a) p (b) Two events A and B are independent 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. WebP(A/B) Formula is the formula used to calculate the conditional probability such that we have to find the probability of event 'A' occurring when event 'B' has occurred. P(A/B) Formula is given as, P(A/B) = P(A∩B) / P(B), where, P(A) is probability of event A happening, P(B) is the probability of event B happening and P(A∩B) is the ...
