A.) Yes, If they attended a public school they are less likely to graduate than if they didn't. 75% is significantly lower than 90%.
B.) 70% of freshmen have a 75% chance of graduating
And 30% of freshmen have a 90% chance of graduating
.75(.70) + .90(.30) = .795 or 79.5% of all freshmen eventually graduate.

A) i'm not sure 🙁 it's worded quite weird.
B) 25/100 = 0.25x10=2.5
Therefore 97.5% eventually graduate.
