Learn Exam P - Probability

General Probability Concepts

1) Sets, Venn Diagrams, Events, and Sample Spaces

• Mutually exclusive (disjoint) vs Non-mutually exclusive (no overlap)
• Union, intersection, and complement of events
• Addition and multiplication rules for probabilities
• Independent and mutually exclusive events
  • Independent events do not affect each other’s probabilities
    • P(A and B) = P(A) * P(B)
  • Mutually exclusive events cannot occur simultaneously
    • P(A or B) = P(A) + P(B)
• Conditional probability

  • P(A	B) = P(A and B) / P(B)
