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>
Answer:
Vertex: (-1/2, -25/4)
Focus: (-1/2, -6)
Axis of Symmetry: x=-1/2
Directrix: y=-13/2
Step-by-step explanation:
x = -2, -1, -1/2, 1, 2
y = -4, -6, -25/4, -4, 0
Prob(first ball being blue) = 6 / (6 + 3 + 3) = 6/12 = 1/2
Prob ( picking a yellow ball) = 3 /12 = 1/4
As the 2 events are independent the probabilities are multiplied
So the answer is 1/2 * 1/4 = 1/8
The less coefficient in front of x^2, the wider graph
the smallest coefficient is 1/5 , so the widest graph is y=(1/5)x²
