Question

Events A and B are independent. Suppose event A occurs with probability 0.62 and event Boccurs with probability 0.67. a. If event A or event Boccurs, what is the probability that both A and B occur? b. If event B occurs, what is the probability that A does not occur? Round your answers to at least two decimal places. (If necessary, consult a list of formulas.) х 5 ? b.
