Confused.

For some reason I do not understand how you got answer D. I watched the video and I guess I may not understand the way the question is setup. Can someone please break it down for me. Thanks!

Okay, so have you watched the video explanation for the game setup? If you're not having an issue understanding the game setup, and merely the question, here's the explanation:

We need to place 5, 6, and 7 in numerical order. Since 7 is on Thursday morning, we have to place 5 on Tuesday afternoon and 6 on Wednesday morning. That is the only way we can place them in numerical order.

Now we still need to place 2 and the other one of 1/3 (whichever isn't use on Monday morning).

So, how many schedules do we have?

We can either place the other of 1/3 on Thursday and 2 on Friday, or we can place 2 on Thursday and the other one of 1/3 on Friday. So that means there are two schedules for 1/3 on Thursday (one with 1 on Monday morning, 3 on Thursday afternoon and 2 on Friday afternoon and another with 3 on Monday morning, 1 on Thursday afternoon and 2 on Friday afternoon) and two schedules for 1/3 on Friday (again one with 1 on Monday morning, 2 on Thursday afternoon and 3 on Friday afternoon and another with 3 on Monday morning, 2 on Thursday afternoon and 1 on Friday afternoon).

So, in total, we have 4 different schedules, which is answer choice (D).

If you have an issue understanding the actual game setup, I would re-watch the video step by step. If you're still have an issue, let me know and we can go over it together.

Hope that clears things up! Please let us know if you have any other questions.
