By  Probability , the number of books that are either science or fiction is 1018.    What is Union and Intersection in Probability?  A set that contains every  element  in at least one of the two sets is called the  union  of two  sets .  A new set that includes every  element  from both sets is created when two sets  intersect .  The formula including  Union  and  Intersection  is :    n(A ∪ B) = n(A) + n(B) – n(A ∩ B)   Let A= Science Books  B = Books of function  A ∪ B = Science Fiction Books  A ∩ B = Either science or fiction Books  n(A)= 463  n(B) = 592  n(A ∩ B) = 37  Therefore,  n(A ∪ B)  is calculated below:  n(A ∪ B) = 463 + 592 - 37  n(A ∪ B) = 1055 - 37  n(A ∪ B) = 1018  Therefore, the  number of books  that are either science or fiction is 1018.
