Hope someone can help

I have a game that I run and im trying to gather statistics on how easy it is to win on an average week

here is the info

In each section of the game there are a 15 possible combinations.

Below is a table that shows the combinations if you were to cover 2(the minumum), 3 , 4 ,5 ,6 games from any section

See the table below.

15 X 15 X 15 X 15(as there ARE 4 SECTIONS =

**50,625** POSSIBLE combinations of playing the game

here are some possible results that the game produces from the criterea given

3 games from Section 1 (3 POSSIBLITIES)

4 games from Section 2 (6 POSSIBLITIES)

2 games from Section 3 (1 POSSIBLITY )

3 games from Section 4 (3 POSSIBLITIES)

3 X 6 X 1 X 3

The combinations are 54

4 games from Section 1 (6 POSSIBLITIES)

4 games from Section 2 (6 POSSIBLITIES)

3 games from Section 3 (3 POSSIBLITIES)

3 games from Section 4 (3 POSSIBLITIES)

6 X 6 X 3 X 3

The combinations are 324

Given my rule that if only 1 selection reaches the criterea how does this apply to the possible combinations.

It seems to make the game easier to win

This week for example

5 games from Section 1 (10 POSSIBLITIES)

1 games from Section 2 (

**?** POSSIBLITIES)

1 games from Section 3 (

**?** POSSIBLITIES)

5 games from Section 4 (10 POSSIBLITIES)

What is the value of

**?** above for working out the possible combinations

Hope this makes sense

Thanks
