Document Summary
Tutorial 1: suppose that vehicles taking a particular highway exit can turn right (r), left (l), or go straight (s), with equal probabilities. Consider observing the direction of each of three successive vehicles. (a) let a be the event of all vehicles going in the same direction. Compute p(a). (b) let b be an event such that all three vehicles take di erent directions. P(b). (c) let c be the event of exactly two vehicles turning right. Compute p(c). (d) list all outcomes in the event d that exactly two vehicles go in the same direction. Of the aircraft that are discovered, 60% have an emergency locator, whereas 90% of the aircraft not discovered do not have such a locator.
