Event E and F have probabilities P(E) = .5,P(F) = 4, and P(E and F) = 2 a. Are E and F mutually exclusive? Explain your answer. b. Are E and Findependent? Explain your answer
Consider two events A and B whose probabilities are known. It is known that the two events are not mutually exclusive and not independent. Which of the following calculations could be used to compute P(A ∩ Bc)? P(A ∩ Bc) = P(A) + P(Bc) P(A ∩ Bc) = P(A) • P(Bc) P(A ∩ Bc) = 1- P(A ∩ B) P(A ∩ Bc) = P(A) - P(A ∩ B)

Two events, A and B, are such that P(A)=.45,P(B) = 65,P( A B)=.25, determine P(AUB). 15. Two events, A and B, are such that P(A)=.45,P(B)=.65,P(AUB)= 7, determine...
Paragraph Styles (a) Use a Venn diagram in which the event areas are proportional to their probabilities to illustrate three non-trivial events A, B, and C that are independent. (b) Provide, if possible, another solution to part (a) that also has P[A] = 0.4 and P[AC] = 0.1. (c) Using a probability table, illustrate three non-trivial events A, B, and C that are pairwise independent but not overall independent (i.e., P[ABC] 6= P[A]P[B]P[C]). Paragraph Styles (a) Use a Venn diagram...
