Your post contains no questions to be answered....
For the Venn diagram....
(1) like all three: given
(2) like rock and classical but not jazz: like rock and classical (given), minus (1)
(3) like rock and jazz but not classical: like rock and jazz (given), minus (1)
(4) like classical and jazz but not rock: like classical and jazz (given), minus (1)
(5) like rock only: like rock (given), minus (1), (2), and (3)
(6) like classical only: like classical (given), minus (1), (2), and (4)
(7) like jazz only: like jazz (given), minus (1), (3), and (4)
(8) like none of the three: the total number of students (given), minus (1) through (7)
