Answer:
Step-by-step explanation:
Given that A denotes some event .
And also given that P(A)=0.999
Here the event [tex]P(\overline{A})[/tex] denotes the complement of event A Therefore [tex]P(\overline{A})[/tex] contains all the events that does not occur in A.
We know that the total probability is 1
So we have that
[tex]P(A)+P(\overline{A})=1[/tex]
[tex]P(\overline{A})=1 -P(A)[/tex]
[tex]=1-0.999[/tex]
[tex]=0.001[/tex]
Hence the complement of event A is [tex]P(\overline{A})=0.001[/tex]
