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)

Answer 1

Answer is 4a



Step by step

Answer 2

Part A:What percentage of the total students surveyed like both watching television and reading?

The total amount of student is 230
The amount of students that like to read and watch television is 80

As a fraction it is 80/230
Turn that to a percentage
It is:34.7826%

Part A=34.7826%

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

On the table it shows 20

So the probability is 20/230

Part B=20/230
