ReportAnswer #1
I made a Venn diagram, showing 12% in the intersection of the "alone" circle and the "group" circle.
It showed 32% falling in the "alone" only part, and 19% falling in the "group" only part.
This left 63% outside the two circles.
Does that mean that 63% don't study at all? Or they study in some other way?

Anyway the probability that they study alone and not in a group is .32
