Step 1
Let P(B) be the probability that event B occurs. We are given: P(A) = 60% = 0.60 P(B | A') = 10% = 0.10, where A' is the event that A does not occur. We want to find the probability that at least one of the events A or B occur, which is P(A or B) or P(A $\cup$ Show more…

21. There is a 60 percent chance that the event A will occur. If A does not occur, then there is a 10 percent chance that B will occur. (a) What is the probability that at least one of the events A or B occurs? (b) If A is the event that the democratic candidate wins the presidential election in 2012 and B is the event that there is a 6.2 or higher earthquake in Los Angeles sometime in 2013, what would you take as the probability that both A and B occur? What assumption are you making?
Madhur L.
Let A and B be two mutually exclusive events. The probability of event A occurring is 50%. The probability of event B occurring is 10%. What is the probability of event A or event B occurring?
Arul S.
Events and are mutually exclusive. Suppose event occurs with probability 0.50 and event B occurs with probability 0.13. If B does not occur; what is the probability that occurs? Round your answer to at least two decimal places:
