HELP PLEASE ASAP!!!!

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)

Respuesta :

                               like t.v.             dont like t.v             total
like reading              70                       10                         80
dont like reading      20                       30                          50
total                          90                      40                         130

percentage of students like t,v and reading : 70/130 = 0.538 = 53.8%

probability of a student who does not like watching t.v. also does not like reading. : 30/40 which reduces to 3/4

A. The percentage of the total students surveyed like both watching television and reading is 53.8%.

B. the probability that a student who does not like watching television also does not like reading is 3 by 4.

  • The calculation is as follows:

like reading              70                       10                         80

dont like reading      20                       30                          50

total                          90                      40                         130

Now

percentage of students like t,v and reading is

[tex]= 70\div 130 [/tex]

= 0.538

= 53.8%

And,

probability of a student who does not like watching t.v. also does not like reading. is

[tex]= 30\div 40 \\\\ = 3\div 4 [/tex]
