Question

If A denotes some​ event, what does Upper A overbar ​denote? If ​P(A)equals0.999​, what is the value of ​P(Upper A overbar​)? What does Upper A overbar ​denote? A. Event Upper A overbar denotes the complement of event​ A, meaning that Upper A overbar and A share some but not all outcomes.

Answer 1

Answer:

The event $P(\overline{A})$ denotes the complement of event A.

The value of $P(\overline{A})$ is 0.001

Step-by-step explanation:

Given that A denotes some event .

And also given that P(A)=0.999

To find the value of $P(\overline{A})$ :

Here the event $P(\overline{A})$ denotes the complement of event A Therefore $P(\overline{A})$ contains all the events that does not occur in A.

We know that the total probability is 1

So we have that

$P(A)+P(\overline{A})=1$

$P(\overline{A})=1 -P(A)$

$=1-0.999$

$=0.001$

Hence the complement of event A is $P(\overline{A})=0.001$

Therefore the value is $P(\overline{A})=0.001$
