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.
