Probability Rules and Operations

Basic Terminology

• Random Process
• Event
• Sample Space

Set Operations(Also see Set theory)

• Union(Or)
  • $P(AorB)=P(A\cup B)=P(A)+P(B)-P(A\cap B)$
• Intersection(And)
  • $P(AandB)=P(A\cap B)$
• Complementary(Not)
  • $P(A^c)=1-P(A)$
• Disjoint
  • Two events are disjoint if $P(A\cap B)=\mathrm{\varnothing }$
