Conditional Probability and the Multiplication Rule It follows from the formula for conditional probability that for any events E and F, PE \F = PFjEPE = PEjFPF: Example Two cards are chosen at random without replacement from a well-shu ed pack, What is the probability that the second card drawn is also a king given that the rst one drawn was a king? 3 51 Example Two cards are chosen

Conditional Probability and Independence One of the most important concepts in the theory of probability is based on the question: How do we modify the probability of an event in light of the fact that something new is known? What is the chance that we will win the game now that we have taken the first point? What is the chance that I am a carrier of a genetic disease now that my first child

CONDITIONAL PROBABILITY Here is another example related to conditional probability although this is not an example of Bayes’ rule This is known as the Monty Hall problem after the host of the TV show in the 60s called Let’s Make a Deal Example 4,7 There are three doors behind one a nice car behind each of the other two a goat eating a bale of straw, ouY choose a door, Then Monty Hall

Conditional Probability Sometimes our computation of the probability of an event is changed by the knowledge that a related event has occurred or is guaranteed to occur or by some additional conditions imposed on the experiment, For example, based on a ,292 batting average for 2016, we might assign probability 29% to Kris Bryant having a hit in his rst at-bat of 2017, But suppose closer to

Examples: Conditional Probability Definition: If PF > 0, then the probability of E given F is defined to be PE,F = PE∩F PF, Example 1 A machine produces parts that are either good 90%, slightly defective 2%, or obviously defective 8%, Pro-duced parts get passed through an automatic inspection machine, which is able to detect any part that is obviously defective and discard it

Deflnition: Let A and B be two events with P[B] > 0 The conditional probability of A given B is deflned to be P[AjB] = P[A\B] P[B] One way to think about this is that if we are told that event B occurs the sample space of interest is now B instead of › and conditional probability is a probability measure on B Joint Conditional, & Marginal Probabilities 4
