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%

I’m pretty sure 86%,C

Step-by-step 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%

Option 'C' is correct.

Step-by-step 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

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

Hence, Option 'C' is correct.

tickets for the harlem globetrotters

show at michigan state university in

2010 cost $16, $23, or, for vip seats, $40.

total revenue = 16x + 23y + 40z

if 9 times as many $16 tickets were sold

as vip tickets,

x = 9z => x – 9z = 0, if 9 times as many $16 tickets were sold

as vip tickets,

x = 9z => x – 9z = 0, sales of all three kinds of tickets would

total $46,575.

16x + 23y + 40z = 46575, how many of each kind of ticket would

have been sold?

solve for x, y and z

x − 9z = 0

x − y − z = 55

16x + 23y + 40z = 46575

x = 1170

y = 985

z = 130

welcome!

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
