Document Summary

Calculating probabilities and events (pnorm and qnorm) P(a or b) = p (a) + p (b) P(a and b) = p (a) p (b) Airline contest study design seats on a plane random) A small airline wants to run a promotional contest for a free trip. They run 3 rounds trips day out of billy bishop airport in toronto with 40. Promotional content will be run one day a month on each flight (at. All passengers will write down their birthday.
