Question 1168186
Lotto Max is won by choosing 7 winning numbers from the number 1 to 49. In how
many ways can a person match [EXACTLY] 4 winning numbers?
<pre>
There are C(7,4) to pick EXACTLY 4 of the winning numbers (no more!).
There are C(42,3) to pick the other 3 as non-winning numbers.

So there are C(7,4)C(42,3) = 401800 ways to pick EXACTLY 4 winning numbers.
