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>

Desmos comes in handy with these problems. Use the "FOIL" method for each of them and then plug them into the calculator of desmos. This will graph each other them. Note the x and y axis'
Example for (A) y= (x-2)(x+3) foil it:
x^2+3x-2x-6
x^2+x-6
plug that in and match to graph.
