A lot of people asked me what kind of probability problems I got on the actual exam. Since I signed a non disclosure agreement, I can't reveal the actual questions, but following are two permutation/combinations- probability problems similar to the ones I got on the real GMAT.
1. There is a set of characters, A B C D E F G H I J K. There are 4 character and 3 character codes to be made out of these characters. What is the ratio of the total number possibilities of the 4 character codes to the total possibilities of the 3 character codes?
2. There are 6 red balls and 3 blue balls in a bag. 2 red balls are taken out. What is the possibility that the next ball taken out will be a red ball? ( Yeah, they are that simple)
