Sequencing on question 11-12

As I was working through the second part of the sequencing games I was a little confused on how setting up the sequence for question 11 and 12 worked. I got the right answer for both but I didn't set up a different sequence as stated in the video. I guess I'm asking is it necessary to have a different sequence from the original large sequence in order to answer these questions more efficiently? Although I got the questions right I want to know the thorough process rather than being lucky.

@Georgio1997, happy to help.

What strategy did you use to find the answers instead?

For #11 of Game 2, you do not need to draw out a new scenario. We can look to our original chain in order to determine which variables could be in the top three- either by eliminating variables from the end of the chain or by identifying those from the beginning that could be in spots 1-3. In fact, it is most time efficient to eliminate these variables from the original chain as the video does, and it is unnecessary to draw out any new specific scenario.

For #12 of Game 2, it is best to draw out a new chain. However, since only one rule is changed, we can do this quickly. Once we have this chain diagrammed, we do not necessarily need to create a scenario. If you're familiar enough with how logic games work, you will likely be able to deduce which variables are determined simply from looking at the new chain itself. If this is the case, it is most time efficient to simply use the chain.

Does that make sense? Please let us know if you have any other questions!
