P (A or B) = P(A) + P(B) P(A and B) also known as Formal Addition Rule: where P (A and B) denotes the probability that A and B ____ occur at the _______ as an outcome in a trial of a procedure.

Events A and B are _______(or mutually exclusive) if they cannot occur at the _____time. (That is, disjoint events do not_______.)

Binomial Distribution is a special case of _________ (Discrete Probability Distribution) . Where it tells us if events are _______ or not. There are ___ categories acceptable/defective.

Event A: Roll a 2 on die Event B: Roll a 5 on die. Event A has an outcome, 2, event B has an outcome, of 5. They ________ occur at the same time, so they are ____________.

The addition rule as a device for finding probabilities that can be expressed as P(A or B), the probability that either event A occurs or event B occurs (or they both occur) as the single outcome of the procedure. The key word in this section is “or.” It is the inclusive or, which means ______ or the ______ or _____.

When three children are born: Assuming that boys and girls are equally likely, find the probability of getting three children of all the same gender P (Three children having the same gender) =  

Intuitive Addition Rule. To find P(A or B), find the sum of the __________ event A can occur and the number of ways event B can occur, adding in such a way that ____________ is counted only ______. P(A or B) is equal to that sum, divided by the total number of outcomes in the sample space.
