a group of students were surveyed to find out if they like watching television or reading during their free time. the results of the survey are shown below:

90 students like watching television
20 students like watching television but do not like reading
80 students like reading
40 students do not like watching television

make a two-way table to represent the data and use the table to answer the following questions.

part a: what percentage of the total students surveyed like both watching television and reading? show your work. (5 points)

part b: what is the probability that a student who does not like watching television also does not like reading? explain your answer. (5 points)
