Answer:
d) 205
Step-by-step explanation:
<u><em>Step(i):-</em></u>
x : 100 150 200 250 300
p(X=x) : 0.10 0.20 0.30 0.30 0.10
<u>Step(ii):-</u>
Let 'X' be the discrete random variable
Expected value of the random variable
E(X) = ∑ x P(X=x)
= 100 X 0.10 + 150 X 0.20 + 200 X 0.30 +250 X 0.30 + 300 X 0.10
= 205
<u>Final answer:</u>-
The expected value E(X) = 205
By using the general equation for a circle, we will see that the correct option is:
(x - 2)^2 + (y - 3)^2 = 36
<h3>
How to find the equation for a circle?</h3>
The general equation for a circle centered at the point (a, b) of radius R is given by:
(x - a)^2 + (y - b)^2 = R^2
In this case, the center is (2, 3) and the radius is R = 6 units, replacing that in the above equation we get:
(x - 2)^2 + (y - 3)^2 = 6^2
(x - 2)^2 + (y - 3)^2 = 36
So the correct option is B.

Probability of survival of one disk, p=1-0.05=0.95
If there are n drives, and failures are independent (e.g. mechanical wear and tear, and not a lightning strike or a current spike), then
Probability of survival = p^n
(a) for two disks, P(2) = 0.95^2=0.9025
(b)for three disks P(3) = 0.95^3 = 0.8574
Answer:
0.1
Step-by-step explanation:
(9/10)/9
= 0.9 / 9
=0.1
