| Addition Rule | 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; keyword = "or" inclusive or (either one or the other or both)

| Compound Event | any event combining 2 or more simple events; NOTATION P(Aor B) = P (in a single trial, event A occurs or event B occurs or they both occur) "find the total in such a way that no outcome is counted more than once"
🗑

| Formal Addition Rule | P(A or B) = P(A) + P(B) - P(A and B); where P(A and B) denotes the probability that A and B both occur at the same time as an outcome in a trial of a procedure
🗑
|

| Disjoint or Mutually Exclusive | Events A and B are disjoint if they cannot occur at the same time. (disjoint events do not overlap)
🗑
|

| Complementary Events | P(A) & P(A-) are disjoint; Rule; P(A)+P(A-)=1
P(A-)+1-P(A); P(A)=1-P(A-)
