Answer: 24 Explanation: You would have to use PEMDAS for this. First, you would multiply -4 x 9 to get -36 then you would multiply that by 2/3 to get -24. Next you would divide -24 by -2 and that would get you a positive 12. Finally you would divide 12 by 1/2 and that would give you 24. Hopefully this makes sense. Heres my work for it too.

So then the correct answer would be:
B) .9996
Step-by-step explanation:
The exact way to solve this problem is using the binomial distribution, assuming that our random variable of interest is "number of students living in apartments" represented by X and
And we want this probability:
So we see that we satisfy the conditions and then we can apply the approximation.
If we appply the approximation the new mean and standard deviation are:
And then
And we are interested on the following probability:
So then the correct answer would be:
B) .9996
