Game diagram help.

Can someone help me diagram this game, please? I'm new to this and having trouble with it.

1.
A college offers one course in each of three subjects - mathematics, nutrition, and oceanography - in the fall and again in the spring. Students' book orders for these course offerings are kept in six folders, numbered 1 through 6, from which labels identifying the folders' contents are missing. The following is known:

Each folder contains only the orders for one of the six course offerings.

Folder 1contains orders for the same subject as folder 2 does.

The orders in folder 3 are for a different subject than are the orders in folder 4.

The fall mathematics orders are in folder 1 or else folder 4.

The spring nutrition orders are not in folder 5.

Re: Game diagram help.

Ok so you have 6 items (courses) to place into 6 slots (folders).

fall:MNO
spring:MNO

Rules:
1.) 1=2
2.) 3=/=4
3.) Mf= 1 or 4
4.) Os= 1 or 4
5.) Ns=/= 5

So since we know 1 = Mf or Os we also know that 2 = Ms or Of (Rule 1)

and then since we know that either both MfMs or both OsOf will be used in 1 and 2 and since 3=/= 4 and 4 must be Os or Mf we know that 3 must be N (though we're not sure if it's the fall or spring). We also know that 5 =/= Ns

Thus we have our initial deductions and diagram:

Mf/Os... Ms/Of... N... Os/Mf... ___... ___
___________________________-Ns

Any questions?

Re: Game diagram help.

Thank you for your help, I get it now.

I'm working through my first mixed bag of games in my prep book, so I was a bit confused having all different games instead of just one specific type to work with.

Once I got through that hurdle, though, it was pretty smooth sailing. Thanks again!
