Questions and Answers

What is the set of all possible outcomes in Venn diagrams?

  • Event
  • Union
  • Intersection
  • Sample Space (correct)

What is the probability rule for the intersection of two independent events?

  • P(A') = 1 - P(A)
  • P(A ∪ B) = P(A) + P(B)
  • P(A ∪ B) = P(A) + P(B) - P(A ∩ B)
  • P(A ∩ B) = P(A) × P(B) (correct)

What is the notation for the set of outcomes that are not in event A?

  • A ∪ B
  • A - B
  • A' (correct)
  • A ∩ B

What is the formula for the probability of the union of three events?

<p>P(A ∪ B ∪ C) = P(A) + P(B) + P(C) - P(A ∩ B) - P(A ∩ C) - P(B ∩ C) (A)</p> Signup and view all the answers
