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

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)

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

Since P(A | B) ≠ P(A), the occurrence of event B the probability that event A will occur. This implies that A and B are not independent events.

Two events A and B are said to mutually exclusive if:Group of answer choicesP(B| A) =1.P(A ∩ B) =1.P(A ∩ B) = 0.P(A| B) = 1.

Given two events, say, and are known to be mutually exclusive events. If the and , what is the probability that both event and event will happen together?Question 1Select one:0.4200.131
