A milk display case at a grocery store is stocked with cartons of regular milk and soy milk, in both normal calorie and lighter calorie options. The number of cartons of each type is divided according to the following table. Let R = the event that the carton contains regular milk, S = the event that the carton contains soy milk, N = the event that the carton has normal caloric content, andL = the event that the carton has lighter caloric content.

Photos and videos have become an important part of the online social experience, with more than half of Internet users posting photos and videos online that they have taken themselves. Let A be the event an Internet user posts photos that he or she has personally taken, and B be the event an Internet user posts videos that he or she has personally taken. Pew Research Center finds that P(A) = 0.52, P(B) = 0.26, and P(A or B) = 0.54. What is the conditional probability that an Internet user posts photos that he or she has personally taken, given that he or she posts videos that he or she has personally taken?
