Algebra please help (lots of points but put work and effort in please):

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.

Part B: What is the probability that a student who does not like watching television also does not like reading?


Lots of info, but please do not be stupid.

Thank you

Answer:

See the attached for the table.


Part A: The desired percentage is

(like both)/(total students) = 70/130 ≈ 54%


Part B: The desired percentage is

(doesn't like reading or TV)/(doesn't like TV) = 30/40 = 75%
