10 cards from this deck
Set of all possible outcomes in a probability experiment
P(S)=1P(S) = 1P(S)=1
P(A∪B)=P(A)+P(B)−P(A∩B)P(A \cup B) = P(A) + P(B) - P(A \cap B)P(A∪B)=P(A)+P(B)−P(A∩B)
Probability that either event A or B (or both) occurs
To avoid double-counting the overlap
Outcomes that belong to both events A and B
P(E)=n(E)n(S)P(E) = \frac{n(E)}{n(S)}P(E)=n(S)n(E)
Between 0 and 1
Add the parts, subtract the overlap
Help visualise why we subtract the intersection
