Guessing Strategies

The lesson provides essential guessing strategies for tackling probability problems on the GRE when the direct solution path is unclear, emphasizing instincts, the complement rule, and understanding overlap.
  • Use your real-world instincts to eliminate highly unlikely answer choices based on the improbability of certain events.
  • Leverage the complement rule to identify pairs of complementary probabilities among the answer choices, which can hint at the correct answer or a common trap.
  • Understand the concept of overlap in probability, recognizing that events with high probabilities are not mutually exclusive and must overlap, which helps in eliminating incorrect answers.
  • Guessing effectively involves eliminating as many wrong answers as possible to increase the odds of selecting the correct answer when unsure.
