Question 59164

rows for "Arts & Science", Business, Education.
columns for male and female.
----------
calculate the row and the column totals

Comment: Your questions are somewhat ambiguous.
For example  Probability of"a female in the 
College Of Arts and Science" could be 65/165
If you limit the choices to the number in the
College of Arts and Science: or the answer 
could be 65/300 if you are only limited by 
the number of students.  I'm going to take
the latter approach and say the answer is 65/300
for question "a".
------------
b) 30/300
c) 135/300
d) 155/300
e) 45/300
-------------
If you construct the contingency table you will 
see the ambiguity I see in your questions.
