For our study, we used the following formula: 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 an example probability question where you could define events A and B to help you answer the question.
