I am having a hard time interpreting different conditional statements in logic games. How should I treat/interpret the rules below?

"For line 3, either the January tickets or the February tickets, but not both, are green." (Game #2 L4 HW, 4-44)
Does this mean that green can be in line 2 for example?


"R is not scheduled for Thursday unless L is scheduled for Monday" (Game #12, L3 HW, 3-58)


Thanks!

Hi C,

Thanks for the question! A few thoughts that might help:


1. We talk about conditional reasoning here and on our blog very frequently, and so there are a ton of places you can go to learn more about diagramming. It's also a topic you'll see in both LR and LG a lot, so it's good that you are asking questions now about it! Here's some articles/threads to review when you have time:





2. "For line 3, either the January tickets or the February tickets, but not both, are green." — On page 4-111 it shows that we've made the diagram directly inside our setup, by shows a G/ alternate on Line 3. Technically, one and exactly one of those two months will be G for Line 3. Since Line 3 is next to Line 2, the two interact, but it's still possible for Line 2 February to be G, but that would then mean Line 3 February could not be G. For example, look at the setup to question #20 on page 4-112: it shows Line 2 as being G.



3. "R is not scheduled for Thursday unless L is scheduled for Monday" — You should use the Unless Equation here (page 2-13), which produces a diagram of RThursday :arrow: LMonday. More on handling Unless here:

4. Last, there's a specific section of the forum for each course, and in this case yours can be found at viewforum.php?f=25. Each lesson and homework has it's own area where you can ask question specifically about course material (and as you might expect, many questions have been answered already) :-D

Please let me know if that helps. thanks!
