The percentage of students that graduated from college that also attended a high school is given as 0.7792 or 77.92 percent.
<h3>How to solve for the probability?</h3>
We have the Prob(attended public school | graduated)
The probability that a person attended public school and graduated as
Prob (P and G) = 0.80 x 0.75
= 0.6
The probability that a person graduated is given as
0.8*0.75 + (1 - 0.8 * 0.85)
= 0.6 + 0.17
= 0.77
Prob(P and G ) /Prob(G)
= 0.6 / 0.77
= 0.7792
The percentage is given as 77.92%

It would be: 63 / 28 = 9 / 4
So, your answer is 9/4
Hope it helped.
"Percent" means " /100 ".
Whatever the number of percent is, write it down as the numerator
of a fraction, and write down 100 for the denominator.
Then look at the fraction, and simplify it if possible, using the
usual techniques for simplifying fractions.
