P(A or B)=P(A) + P(B) – P(A and B) (a) Is it ever possible that P(A) = 4.3? Explain why or why not. (b) What would need to be true about A and B to ensure that P(A and B) = 0? Justify your answer. Feel free to use create an example probability question where you could define events A and B to help you answer the question.
