Question

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​)?

Answer 1

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
