The event that exactly one of the events A or B occurs can be represented as (A intersection B') U (A' intersection B).  Show that P[(A intersection B') U (A' intersection B)] = P(A)+P(B) - 2P(A intersection B)

Extracted text: The event that exactly one of the events A or B occurs can be represented as (An B') U (A'n B). Show that P[(A n B') U (A' n B)] = P(A) + P(B) – 2P(A n B) %3D
