            This problem is SPECIAL.
            It is special, because you do not need to think to solve it.
            You simply write formulas as you read the text.

First, calculate the total number of people in the table

     4746 + 4517 + 1625 + 1553 + 1679 + 1627 = 15747.


Now


(a)  P = .                       Use your calculator.



(b)  P = .    Use your calculator.



(c)  P = .    Use your calculator.

The formulas are self-explanatory.

You even do not need to know a formal definition of what the probability is.

The common sense and a bit of intuition at the level of advanced kindergarten alumni is enough
to solve this problem to the end without any help from outside.
