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. (I've already done this)

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)

(I'm horrible with percentages ;-;")
