Question

Given the venn diagram below, if a student is randomly selected, what is the probability that he or she is not attending both colleges?

A) 82%
B) 84%
C) 86%
D) 80%

Answer 1

Answer: I’m pretty sure 86%,C

Explanation:

Add up all the numbers provided (64+28+52+56)=200.

Then divide 28 by 200 this is 14. After, subtract 100%-14%, therefore you get 86%

Answer 2

Answer: Option 'C' is correct.

Explanation:

Since we have given that

Number of people attended Texas only = 64

Number of people attended Binn = 52

Number of people attended both = 28

Number of people not attending any colleges = 56

Total number of people = 64+52+28+56 = 200

Probability of people attending both is given by

`(28)/(200)* 100\\\\=14\%`

So, Probability of people not attending both colleges is given by

`100\%-14\%\\\\=86\%`

Hence, Option 'C' is correct.
