Sure, but what about Trick IMPLIES Treat?

It would be ((trick nor treat) or treat) so basically all the non-circle region and the treat circle is filled............

After writing this, i am wondering if you actually needed the information or was it just the funny thing to say...

Guys am I autistic?

I had to double-take since in Python a common alternative to

`trick ? treat : notreat`

is`(trick and treat) or notreat`

But I don't think this translates to overlapping circles very well. "trick implies treat" is only defined inside the trick circle, outside is undefined if treat is true or not.

I'm not going to draw a diagram, but here's the "truth table" for A implies B:

`A, B, A -> B N, N, undefined N, Y, undefined Y, N, false Y, Y, true`

If A is false, A -> B is true regardless of what B is, so the two undefined terms in your truth table should be true.

So it is fairly easily translated into a shaded Venn Diagram. It's simply everything shaded aside from Trick only.
