First of all, we need to deduce the price of a single camera:
Now, we know that he profits 36 dollars from each camera. So, we are asking: which percentage of 150 is 36? We have
This equation literally says: 36 is x-percent of 150. And we need to solve for x:
The value of the missing probability is:
P(A) = 1/5
So the correct option is D.
<h3>How to find the missing probability?</h3>
First, we know that:
P(A∩B) = probability that events A and B are true = 3/100
And we also know that:
P(B|A) = probability that event B is true given that event A is true = 3/20
Here we have the rule:
P(A∩B) = P(B|A)*P(A)
Replacing the first two:
3/100 = (3/20)*P(A)
Solving for P(A), we get:
(3/100)*(20/3) = 1/5 = P(A).
So we conclude that the correct option for the missing probability is the one in option D.

The easiest way to work this out is to first find 10% of 850 which is 85. From there I would divide 85 by two, this gives us 43% rounded. To find 25% simply times 85 by 2 and add on the 43. Your answer should be 213.
