## Setup and Rule Diagrams

Hi Carolyn!

So just from our first 2 rules, we can create this basic setup:

F
G K
H

The 3rd rule is trickier to put in our diagram so let's come back to it. The fourth rule presents two scenarios: either M comes before H or after K. So now our setup follows two different possibilities.

Possibility 1:

F
G K
M H

Possibility 2:

F
G K M
H

Ok, back to the 3rd rule, which tells us that if F is before M, then L is before H. Is F definitively before M in either of our possibilities? Yes, in possibility 2. So our final setup will look like this:

Possibility 1:

F
G K
M H

Possibility 2:

F
G K M
L H

In the second possibility, we have all the variables accounted for. In the first one, though, we still can't say where L goes. However, it can't quite go anywhere, since its placement is still limited by our second rule (for example: if we're in the first template, but we learn that F goes first, then we know L has to come before H and can therefore can only go second or third). So as we're answering the questions, the key is to figure out what template we're operating in. If we're in the second one, the order is accounted for by our diagram. If we're in the first one, we have to keep a close eye on where L goes.

Hope that helps!

Hello. I would just like to check my understanding of rule #3.
If L is 6th is this the outcome from 1-6?
M F/H F/H G K L

Also, I understand from the discussion above that using the contrapositive of rule #3 would not have yielded all possibilities. My question is, would a third scenario of L-H yield all possibilities?

Your proposed scenario with L 6th is valid, haganski! And it fits neatly into the first template that we described, the one based on M being before both H and K. In that template, L is random, so it can go anywhere in the sequence.

Often a conditional rule leads to three templates: 1) the sufficient occurs, the necessary occurs; 2) the necessary does not occur, the sufficient does not occur; and 3) the necessary occurs but the sufficient does not (in other words, the rule is simply not triggered). However, in this case there is no need for that additional template, because our first template includes that possibility. We based the templates not on the conditional third rule, but on the sequence rule four.

Good work!

Hi there,

I really struggled with this game, but I can't seem to find others like it in the pure sequencing drill sets. Do y'all happen to know of any more sequencing games that have conditional elements (and so need multiple diagrams to contain all the possibilities) that I could practice with?

Thanks!

I once made a list of these and similar games, so this would be a good place to start:

PT 51 Game 2 (hotel suites)
PT 61 Game 2 (artifacts)
PT 63 Game 2 (skydiving)
PT 63 Game 3 (vehicles)
PT 73 Game 1 (CD)
PT 74 Game 1 (band)
PT 78 Game 3 (antiques)
PT 83 Game 2 (concert)
PT 87 Game 1 (expert witness)

Hope this helps!
