Im working on a lottery system for my board... Just for its birthday :-)

We are having 5 prizes...

I need someone to work out how many balls out of a selecion of ??? balls would be needed to have a good probability that this will be the likely outcome... :-

1st Prize) 1 winner

2nd Prize) 3 winners

3rd Prize) 8 winners

4th prize) 10 winners

5th prize) 17 winners

The number of winners can be slightly changed... We have 1104 members and there are usually 20 members online 30 max but I think there will be alot more on board for the boards birthday

He he I was never any good at maths
