Can someone pls help me fast?! I will give u brainlist!

Part A: Part A: About 53.8% of the students like both reading and watching television. I know this because if you add up all the students surveyed then you get 130 (70 + 20 + 10 + 30 = 130). Then if you divide 70 ÷ 130 you get 0.538. The you multiply by 100, and you get 53.8%.

Part B: The probability would be 75%. I know this because if there is a total of 40 people that do not like watching TV and there are 30 that do not like reading and do not like watching TV either, Then you divide 30 ÷ 40 then you would get 0.75 then you multiply that by 100 to get an answer of 75%.

Step-by-Step Explanation:

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
