12- 8 Probability of Compound Events Objective: Find probabilities of exclusive and overlapping events and independent and dependent
12- 8 Probability of Compound Events Compound Event: Is the possibility of two or more events linked with the word And or the word OR.
12- 8 Probability of Compound Events Mutually exclusive: can’t happen at same time P(A or B) = P(A) + P(B) Overlapping events can happen at same time P(A or B) = P(A) + P(B) – P(A and B)
12- 8 Probability of Compound Events Spinner has 20 sections numbered 1 to 10. Probability of spinning a 2 or a 5? Can’t land on both at same time so events are exclusive. P(2 or 5) = P(2) + P(5)
12- 8 Probability of Compound Events
Independent events if the occurrence of one event does not effect the other. P(A and B) = P(A) ∙ P(B)
12- 8 Probability of Compound Events
Two events are dependent if one event affects the probability of the second event. Choose and NOT replace the object. A and B are dependent events; P(A then B) = P(A) ∙ P(B after A)

I can find probabilities of compound events.. Compound Events Involves two or more things happening at once. Uses the words “and” & “or”
13-4 Compound Probability. Compound Event: an event that is made up of two or more events Independent Even: if the occurrence of an event DOES NOT affect.
Section 3.2 Notes Conditional Probability. Conditional probability is the probability of an event occurring, given that another event has already occurred.
Lesson 53 – Introduction to Probability Math 2 Honors - Santowski.
Probability COMPOUND EVENTS. If two sets or events have no elements in common, they are called disjoint or mutually exclusive. Examples of mutually exclusive.
To find the probability of two events occurring together, you have to decide whether one even occurring affects the other event. * Dependent Events—the.
