Disjoint events have no outcomes in common and with P(A or B)=P(A)+P(B). If this equality does not hold, the events are not disjoint. Which of the following events are disjoint? a. P(A)=0.30, P(B)=0.25 and P(A or B)=0.55 b. P(A)=0.30, P(B)=0.15 and P(A or B)=0.35 c. P(A)=0.60, P(B)=0.50 and P(A or B)=0.75 d. P(A)=0.40, P(B)=0.40 and P(A or B)=0.70

Consider two events A and B with respective probabilities P(A) and P(B). Which of the following represent the probabilities corresponding to the case where events A and B are disjoint? (Note that disjoint events have no outcomes in common.) P(A) = 0.20, P(B) = 0.35, and P(A or B) = 0.55 P(A) = 0.35, P(B) = 0.45, and P(A or B) = 0.50 P(A) = 0.55, P(B) = 0.25, and P(A or B) = 0.70 P(A) = 0.40, P(B) = 0.45, and P(A or B) = 0.75
