Answer 6

Lets put it this way.
What is the probability that a student, out of all students, plays both guitar and tuba (no matter whether he plays trombone or not).

There are 15 people who play both tube and guitar,
AND there are 92 students overall.

The probability (as a fraction) 15/92. (that can't be reduced)
As percent: (about) 16.3 %
