In a college 26% students are business majors, 38% are majors in humanities; and
between the two there are 12% double majors in business and humanities. If we pick a
student at random, (i) what is the chance that the student will be a business major, or
humanities major or both? (ii) If the student picked is a business major, what is the
chance that he/she is also a double major in humanities? (iii) what is the chance that the
student will be a business major only?
