"A television executive is deciding the scheduling for five advertisements - A, B, C, D, and E - to be aired during one week, from Monday through Friday. The schedule must accord with the following:

Exactly one advertisement is scheduled to air each day.
No advertisement can air more than two days per week."

The book mentions that, "From the perspective of the advertisement-to-days, yes, a single advertisement is aired each day (1-1-1-1-1). But, nowhere in the rules does it state that each advertisement must be aired, and so some advertisements can air more than once and other advertisements do not have to air at all. This is a critical piece of information, and it creates three distributions of days to advertisements:"

2-2-1-0-0
2-1-1-1-0
1-1-1-1-1

How can this be in light of the first rule ("Exactly one advertisement is scheduled to air each day.")?

Yes, there is a difference between "scheduled to air" and actually "airing."

[CicBob17]

Those breakdowns are number of days an ad is shown. 2-2-1-0-0 means two ads shown twice, one shown once, and the others not shown. still only one per day M-F

I think you misunderstand that rule as "No ad can air more than once" or "Each ad must air"
The stated rule only dictates that no more than one ad can air in a given day.

Thank you. I understand now.

Sorry to post old thread, but I am confused and hope that someone can clarify this information for me.

"exactly one advertisement is scheduled to air each day." - Yes, this does not say that each one must air, but it does state that EXACTLY ONE is scheduled - Therefore, I am not sure how a "2-2-1-0-0" could work, as at least one ad must advertise

"No advertisement can air more than two days per week" - Which allows me to know that up to two advertisement can run in the week.

That being said - and because there are 5 advertisements - then it is possible for all 5 to be shown exactly 2 times. If all used twice (6-1-1-1-1), (5-2-1-1-1), (4-3-1-1-1), (4-2-2-1-1), (3-3-2-1-1), (3-2-2-2-1), (2-2-2-2-2).

I also understand that some might not be used, so it could have an order like (2-2-1-1-1),(4-2-1-1-1), etc.

But given the information and the rules I fail to see how the order could ever be (2-2-1-0-0) as "exactly one advertisement is scheduled to air each day"

Hope this was straightforward enough, and thanks in advance!

(2-2-1-0-0) isn't meant to indicate that no advertisements aired the final two days, but rather it shows that two advertisements could be aired twice, one once, and two not at all, such as Day 1 (A) / Day 2 (A) / Day 3 (B) / Day 4 (B) / Day 5 (C). The "0-0" reflects the fact that in this scenario D and E are not shown at all.

This is because nowhere in the rules does it stipulate that each advertisement must be aired, only that one advertisement must be shown each day, and that the maximum number of times each can be shown is twice.
