Event ? is always unlikely. O B. Events A and A share all outcomes. O C. Event A denotes the complement of event A, meaning that À consists of all outcomes in which event A does not occur O D. Event A denotes the complement of event A, meaning that A and A share some but not a# outcomes. Click to select your answer and then click Check Answer clear All parts remaining

Explanation / Answer

Answer is option C.

Abar denotes the complement of A. That is, Abar contains all the outcomes that are not occuring in event A. This means, P(A)+P(Abar) = 1.

So, if P(A) = 0.003, then P(Abar) = 1-0.003 = 0.997, so Abar is not unlikely.
