I've been doing this basic Statistics Project and I'm puzzled as to how to calculate the probabilities for winning numbers. Even more so since I live in Holland and I'm using the Dutch Lotto as framework. Here the Lotto is 6/45. However, there is a 7th Bonus

*and*Colour ball which gives a little extra.

So, you can get:

All 6 numbers or

5 numbers + colour + bonus (the bonus ball decides the colour)

5 numbers + bonus

5 numbers + colour

5 numbers

so on...

to at last 2 matching numbers.

How would I calculate the probabilities for obtaining each? If not for this game, how about for a 6/4X game? Are there any sites out there which can help me out on this? Thx for reading.
