I'm taking the GMAT a second time on Friday (5/30/08) and I'm having difficulty grasping Discrete Probability.
Since my goal is to score moderately (~530), and I only need to be above the 50th percentile for the program I'm applying to, is this concept essential for me to score within my desired range on the exam? I appreciate the help.
BTW, I have posted my situation http://gmatclub.com/forum/8-p461656?t=63264#p461656
for more background on my situation. Thanks!
