WebbDefinition: A ∩ B Given two sets A and B, define their intersection to be the set A ∩ B = {x ∈ U ∣ x ∈ A ∧ x ∈ B} Loosely speaking, A ∩ B contains elements common to both A and B. Definition: A ∪ B The union of A and B is defined as A ∪ B = {x ∈ U ∣ x ∈ A ∨ x ∈ B} Thus A ∪ B is, as the name suggests, the set combining all the elements from A and B.

WebbThe intersection of events A and B, denoted A ∩ B, is the collection of all outcomes that are elements of both of the sets A and B. It corresponds to combining descriptions of the two events using the word “and.” To say that the event A ∩ B occurred means that on a particular trial of the experiment both A and B occurred. WebbThis means that the complement of their intersection is the entire sample space, which has a probability of one. Or more formally, we can say that the probability of 𝐴 intersect 𝐵 complement is one minus the probability of 𝐴 intersect 𝐵. That’s …
