Using this Venn diagram, what is the probability that event A or event B occurs?  0.60  0.78  0.42  0.22 RATIONALE To find the probability that event A or event B occurs, we can use the following formula for overlapping events: The probability of event A is ALL of circle A, or 0.39 + 0.18 = 0.57. The probability of event B is ALL of circle B, or 0.21 + 0.18 = 0.39. The probability of event A and B is the intersection of the Venn diagram, or 0.18. We can also simply a...
