11. 1/6 = what %






12. Probability and Geometry.






13. In general - difficult questions require how many steps to solve?






14. Some GMAT word problems involve groups with distinct 'either/or' categories (male/female - blue collar/white collar - etc.) The key is to do what with the information? 1. Find total number of possible outcomes. 2. Find the number of desired outcomes.
