The example used on the top of the page 546 specifies in the first rule that “exactly one advertisement is scheduled to air each day,” however two of the three possible distributions listed include at least one day with no advertisements scheduled and at least one day with more than one scheduled, as follows:


How does that not violate the rule cited above?

Thank you for clarifying this.

Hi Road,

Thanks for the question! Take a closer look at what the distribution represents: the number of time each of the 5 advertisements airs. It does NOT represent how many ads appear each day, as that is fixed at 1-1-1-1-1.

If you look at each distribution, you'll note how it states things like, "Two advertisements air twice, one advertisement airs once, and two
advertisements do not air." this means that each number ultimately corresponds to an advertisement (namely A, B, C, D, and E) and those numbers indicate how many times each will air (but they aren't in A, B, C, D, and E order).

Just to be clear, looking at that first distribution for example, the 2-2-1-0-0 means that two of the ads air twice (that's the 2-2 part, which could be any two of A, B, C, D, and E), one ad airs a single time (1), and at that point we have our 5 ads for the week since there will always be 5. There's no room for the other two ads, and thus they don't air (0-0).

Please let me know if that helps. Thanks!
