If a year is randomly selected, find the probability that Thanksgiving Day in the U.S. is Example: on a) Wednesday; b) Thursday Complement Example: (Complement of a smoker) We found earlier that P(smoker) = = .20. Find the probability of randomly selecting an adult in the U.S. who does not smoke. Rounding off Probabilities Example: Probability of 0.8208356 Probability of 0.0357469 Probability of 2/3 Probability of 4/8 Probability of 0.0002546 Interpreting Probabilities An event is unlikely An event has an unusually low number An event has an unusually high number
