❓ Frequently Asked Questions
What is probability, and how is it typically calculated in puzzles?
Probability measures how likely an event is. For fair, simple scenarios, P(E) = number of favorable outcomes / total outcomes in the sample space. Puzzles often use counting, symmetry, or listing outcomes to compute this.
How can you tell if events are independent or dependent?
Independent events don't affect each other’s outcome (e.g., coin flips). Dependent events do (e.g., drawing cards without replacement). For independent: P(A∩B) = P(A)P(B); for dependent: P(A∩B) = P(A)P(B|A).
What is conditional probability and why is it useful in puzzles?
Conditional probability is the probability of an event given that another has occurred: P(A|B) = P(A∩B)/P(B). It helps update chances when new information is known.
What quick tricks can simplify probability puzzles?
Use the complement (P(at least one) = 1 − P(none)); use symmetry to reduce cases; break problems into cases or count favorable vs. total outcomes.
