Which the following probability notations denotes the probability of event A occurring or event B occurring or both?Group of answer choicesP(A and B)P(A or B)P(not A)P(A)

For P(A or B), "or" is inclusive, it it includes the possibility that both event A and event B happen.

Let A and B be mutually exclusive events. Which of the following is always TRUE for these events?Group of answer choicesP(A and B) = P(A) x P(B)P(A or B) = P(A) + P(B)P(A or B) = P(A) + P(B) - P(A) x P(B)all of the above are always true

What is the normal notation for the probability of the occurence of one event A given the occurence of another event B ? P(B) AND P(A) P(B,A) P(A) <- P(B) P(A|B)

If A and B are independent events, with P(A) = 0.50 and P(B) = 0.70, then the probability that A occurs or B occurs or both occur is:Group of answer choices0.10.0.20.1.20.0.85.
