Question #1019

Diagramming either/or

In the video, instead of diagramming either/or as was done in the sufficient / necessary lecture (by picking one of the two either/or variables as the sufficient condition and negating it), you diagrammed the either/or statement as a necessary condition of the high sales volume sufficient condition. How do you know when to diagram it as part of another condition, or when to diagram it on its own?

    @egracer notice here it is not a simple either/or statement. Rather our "either/or" is actually part of the necessary condition that is being introduced with "must." "To generate such volume, bookstores MUST either cater to mass tastes or have exclusive access to large specialized market, such as medical textbooks, or both." So this principle would be diagrammed as follows: HSV ==> CM or EA or both not CM & not EA ==> not HSV Hope that helps! Please let us know if you have any other questions.

    Question 8 for Sufficient and Necessary Questions, I still do not get why you are saying d-hsv when we do not get discounts for higher sales profit. I get that you are negating it but can you explain it in another way? Because I am not getting your explanation. Thank you

    @julia, the statement is not saying that you cannot get discounts even if you have higher sales volume but rather that you cannot get a discount unless you have a high sales volume. Does that answer your question?
