Summary
The lesson provides essential guessing strategies for tackling probability problems on the GRE, focusing on using instincts, the complement rule, and understanding overlap to make educated guesses.
  • Use real-world instincts to eliminate highly unlikely answer choices based on the scenario's plausibility.
  • Employ the complement rule to identify and eliminate trap answers, especially in 'at least one' probability questions.
  • Understand the concept of overlap in probability to estimate the minimum and maximum possible values for 'AND' and 'OR' scenarios, aiding in answer elimination.
  • Recognize that even without complete understanding, strategic guessing can significantly improve odds of selecting the correct answer.
