The square of a binomial is written like

In your case, you have 
, which implies 
So, we want to write

But our left hand side is

If we add 26 to both sides, we have

 
        
             
        
        
        
1/4 the students in study hall (per 7) = 16
16*4 = 64 students in study hall.

Answer:
The probability that the selected person is a woman engineering major is 0.0396.
Step-by-step explanation:
The proportion of students at the university who are women is 0.42.
<em>P (W) = 0.42</em>
The proportion of students at the university who are engineering majors is 0.18.
<em>P (E) = 0.18</em>
The proportion of engineering majors that are women is 0.22.
<em>P (W|E) = 0.22</em>
The proportion of students at the university that are woman and engineering major is:

Thus, the probability that the selected person is a woman engineering major is 0.0396.
