Is the probability of “A given B” the same as the probability of “B given A?” Explain. In general (whether events are independent or not), what is the formula for finding ? Explain the difference between the Multiplication Rule for independent events and the General Multiplication Rule. State the formula used to determine whether or not ...

Rearranging the Conditional Probability Formula, we get: Probability of Intersection of Two Events. P(A ∩ B) = P(B) P(A | B) or P(A ∩ B) = P(A) P(B | A) Example 4(b): An auto-parts store purchases 30% of its lamps from the Acme manufacturer. Estimate the probability that a randomly chosen lamp in the store is from Acme and is ...
Conditional Probability
P(A|B) is read as the probability of A given B. It is the probability that A will occur if we know that B has occurred or will occur. P(A|B) is sometimes called revised probability because you are recalculating a probability with new information.

P(A | B) = probability that event A occurs given that event B occurs when the experiment is conducted. Recall die roll example: A = {roll even number}, B = {roll number less than 4} What is the probability of rolling an even number given that we roll a number less than 4? Intuitively: Formula: P(A | B) = P(A ∩ B) (assuming P(B) ≠ 0) P(B)

Hence the probability of the Queen of Hearts, given the Red Card sub-Universe (given means with the knowledge that the event that occurs is in that sub-universe), is 1/52 divided by 1/2, or 1/26. This is traditionally written: p(A|B) = probability of A, given B = . Guessing a word, given knowledge of …
