    Red face Hard Question! Please Answer!

    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,
    or its just badly posed.

    Either way you won't get a sensible answer to this question without
    you providing/obtaining more information.
