# Logic games pg 177 conflict

On pg 177 of your book it gives this question example and rule:

Thomas is baking pies for five friends M,N,O,P and R. Each pie will have at least one of six ingredients: F,G,H,J,K, and L. The following rules apply:

Possible rule 1: If a pie has F & G, it must also have J.

Then it states in the book the obvious, that if you have F & G -> J, but then it says you can’t have J without F & G, which is not what the rule says at all, and completely conflicts with the prior lesson/example.

If you know the pie has F & G then the rule states you must also have J. The rule doesn’t say that if you have J, you must have F & G?

Could someone clarify?

Hey Thomas — happy to try and help try and figure out what’s going on — where do you see that I say you can’t have J without F and G? — I can’t find where I’ve written that — thanks — MK
