Lets say we were asking a probability question. we had 69 people with an average in the range of 71-80%. We had 24 people who spent 1-4 hours on extra cirricular activities. How could we figure out how many people with the 71-80% avg spent 1-4 hours on activities?
SO TO RECAP: The probability of students getting a 71-80 average while doing 1-4 hours activities?

This is a hard question because either you have not provided all the
information that you have, and so we don't have enough to solve this,
