Step-by-step explanation:
Answer:
<h3>The event

denotes the complement of event A.</h3><h3>The value of

is 0.001</h3>
Step-by-step explanation:
Given that A denotes some event .
And also given that P(A)=0.999
<h3>To find the value of

:</h3>
Here the event
denotes the complement of event A Therefore
contains all the events that does not occur in A.
We know that the total probability is 1
So we have that




Hence the complement of event A is 
<h3>Therefore the value is

</h3>
It is 9 because you have a 30,60,90 triangle, and then you can use pythagorean theorem.
