If a denotes some event, what does upper a overbar denote? if p (a) equals0.992 , what is the value of p (upper a overbar ) ?

If A denotes some event, what does Ā denote?

If P (A) = 0.992, what is the value of P (Ā) ?

Answer:

A denotes some event, Ā denotes the complement of A that is Ā contains all the events that does not occur in A.

Given: P (A) = 0.992

We know total probability = 1

P (A) + P (Ā) = 1

P (Ā) = 1 - P (A)

P (Ā) = 1 - 0.992 = 0.008

P (Ā) = 0.008
