Question

https://gmatclub.com/forum/download/file.php?id=81973 Associations A through E are sponsoring a certain professional conference. Each of the attendees of this conference is a member of at least two of these sponsoring organizations. On the conference registration form, each attendee indicated which of these associations he or she considers to be primary and which he or she considers to be secondary. No attendee listed the same association as both primary and secondary. The graph shows these registration results for the 80 attendees. Select from each drop-down menu the option that creates the most accurate statement about the attendees of this conference. Association GRAPH_1_PLACEHOLDER is more than twice as likely to be listed as a randomly selected attendee’s secondary association than as the attendee's primary association. Of the five associations, Association GRAPH_2_PLACEHOLDER is most likely to be among a randomly selected attendee's associations (primary or secondary). GMAT-Club-Forum-ha4h6fex.jpeg

DD 1: sec = 2 times primary --> only green Ass "C" looks like it.
DD 2: primary or sec red has max favourable outcomes

Fr DD2, I think the answer could go either way, if one have to compare the total amount of primary and second COMBINED.

A: 29+26 = 55
B: 27+27 B = 54

BUT I guess the word "(primary or secondary)" means pick EITHER one (primary or secondary) that show greater amount in comparison between A and B

We have 80 attendees, if an attendee is chosen/selected randomnly, the association that was considered as either his primary choice or the secondary choice, the probability of it being Association A is higher, as it is considered as a primary by 34 attendees and secondary by 26. 34+26=60 the probability is higher clearly which is not the case for others. In case of B, its considered Primary by 26 attendees and secondary by 27 attendees, 26+27 = 53.

Associations A through E are sponsoring a certain professional conference. Each of the attendees of this conference is a member of at least two of these sponsoring organizations. On the conference registration form, each attendee indicated which of these associations he or she considers to be primary and which he or she considers to be secondary. No attendee listed the same association as both primary and secondary. The graph shows these registration results for the 80 attendees.

Select from each drop-down menu the option that creates the most accurate statement about the attendees of this conference.

Association  GRAPH_1_PLACEHOLDER  is more than twice as likely to be listed as a randomly selected attendee’s secondary association than as the attendee's primary association.

Of the five associations, Association  GRAPH_2_PLACEHOLDER  is most likely to be among a randomly selected attendee's associations (primary or secondary).

Drop-down 1:

We are asked which association is more than twice as likely to be chosen as secondary than as primary. That means its secondary bar must be more than double its primary bar. Only C satisfies this, so the answer is C.

Drop-down 2:

We are asked which association is most likely to appear in someone’s overall set of associations. That just means which one has the largest total bar (primary plus secondary). A has the biggest overall bar, so the answer is A.
