Question 278202
A lottery is run using balls labeled 1 - 100. To win you must pick the seven balls chosen
randomly without replacement (numbers cannot be picked twice). What is the
probability of winning the lottery?
--------------------------
There is one set of seven balls that wins
There are 100C7 = 16007560800 sets of seven balls possible.
----
The probability of getting that set of seven balls is 
1/16,007,560,800
---
That answer is not exactly correct.  My calculator only shows
nine digit places but indicates there are two more.
