Hey guys,

Im preparing for the GRE Exam and I am finding these quantitative reasoning problems quite difficult...I am so awful at Math. I am not sure this is the right thread for this question, please forgive me if it isn't..

So this is the problem:

The total number of recording titles distributed by music distributorsLandMis 9,300. The number of recording titles distributed byLis 7,100 and the number of recording titles distributed byMis 5,200. Which of the following statements MUST be true?

a. More than half the titles distributed by L are also distributed by M

b. More than half the titles distributed by M are also distributed by L

c. No titles are distributed by both L and M

Is this a probability problem? Any tips would be appreciated...
