Let A denote the event it is defective
and B denote the event that it is not made by Ratten company.
Lens Defective Not Defective Total .
Greens 5% 55% 60% .
Parsons 10% 5% 15% .
Ratten 6% 19% 25% .
Total 21% 79% 100%
P(A)=0.21
( Since 21/100=0.21 )
P(A∩B)= 15%
( Since, 5%+10%=15%
and 15%/100%=0.15)
Hence, we are asked to find P(B|A)
We know that:

The answer is:
0.71
The maximum number of mosquitoes would exist if 7.5 inches of rain fell.
We can find that by looking for the maximum value in the equation. This value always falls at the vertex. The x-value of the vertex (which is what we are looking for) can always be found through the equation -b/2a, in which a is equal to the coefficient of x^2 (-1) and b is equal to the coefficient of x (15).
-b/2a
-(15)/2(-1)
-15/-2
