We use the binomial distribution:
In this formula, <em>c</em> is the acceptable number of defectives; <em>n</em> is the sample size; <em>p</em> is the fraction of defectives in the population. Our <em>c</em> is 2; <em>n</em> is 58; and <em /><em>p</em> is 0.11. Once we evaluate that summation, we get 0.0388. This has a 3.88% chance of being accepted. Since this is such a low chance, we can expect many of the shipments like this to be rejected.

Answer:
Option C.
Step-by-step explanation:
We start with the expression:
where y > 0. (this allow us to have y inside a square root, so we don't mess with complex numbers)
We want to find the equivalent expression to this one.
Here, we can do the next two simplifications:
And:
If we apply these two to our initial expression, we can rewrite it as:
Here we can use the second simplification again, to rewrite:
So, concluding, we have:
Then the correct option is C.
