The conditional probability that event A occurs, given that event B has occurred, is calculated as follows: P(A|B) = P(A∩B) / P(B) where: P(A∩B) = the probability that event A and event B both occur. A table of the range of numerical values is given, as well as the probabilities that correspond to them: When using this statistical function, it is necessary to calculate the probability of an event that the … - [Instructor] Here, we cover a type…of probability called conditional probability.…Sometimes, an event, (B), influences the probability…of occurrence another event, (A).…This is called conditional probability.…We symbolize it this way, and we say the probability…that A occurs given that B occurs,…or probability of A given B,…so that vertical line corresponds to given.…, Here's an example of conditional probability.…I toss the die, and I tell you…that the result is an even number.…I'll call that event B.…What's the probability that it's a four?…I'll call four event A.…Thinking it through, the probability of A given B,…the probability of four given…that it's an even number, is 1/3.…We've got one four, or we've got three even numbers,…so one over three.…, So what's the probability of a four conditional…on an even number as result of the toss?…In this example, the effect of conditional probability…is to narrow down the number of elementary outcomes…in the sample space.…If we don't know that an even number occurred,…the probability of a four is 1/6.…. 4. You can pick up where you left off, or start over.
