Answer 1

Uh, I don't really understand Part 1.

Part B: 5% of the survey respondents did not like either beef or chicken.

Part C: The survey results show a greater dislike of beef. 20 people dislike beef but like chicken. 15 people like beef, but not chicken. 

5 don't like both.

Answer 2

                        like beef.......do not like beef......total
like chicken         60                   20                     80
do not like c        15                     5                      20
-------------------------------------------------------------------------
total                     75                   25                     100

B. did not like beef or chicken.....5/100 = 0.05 = 5%
C. the survey reveals a greater dislike for beef...because 15% like just beef, but 20% like just chicken
