ABSTRACT
Operation Read as Definition A ∪B A union B The elements in A or in B A ∩B A intersection B The elements in both A and B A−B A minus B The elements in A which are not in B A′ or A or AC Complement of A The elements in U which are not in A P(A) or 2A Power set of A The collection of all subsets of A A⊕B or A∆B Symmetric difference
of A and B The elements of A and B that are not in both A and B (i.e., the union minus the intersection)
3.1.3 CONNECTION BETWEEN SETS AND PROBABILITY Set concept Probability concept Set Event Set containing a single element Indecomposable, elementary, or
atomic event Set with more than one element Compound event Universal set or space Sample space Complement of a set Non-occurrence of an event Function on the universal set Random variable Measure of a set Probability of an event Integral with respect to the measure Expectation or expected value
3.1.4 VENN DIAGRAMS The operations and relations on sets can be illustrated by Venn diagrams. The diagrams below show a few possibilities.
