Using Area to Find Geometric Probability
... Using Length to Find Geometric Probability You are visiting San Francisco and are taking a trolley ride to a store on Market Street. You are supposed to meet a friend at a store at 3:00 PM The trolley runs every 10 minutes and the trip to the store is 8 minutes. You arrive at the trolley stop at 2: ...

... more than 50%? Unfortunately even this connection is not so clear-cut. A classic example involves 1,000 people attending an event at which only 499 admission fares were collected. This means that a randomly-chosen attendee has probability 50.1% of not having paid admission. But surely no judge would ...

... We will ignore here the possibility of ties (so this simplified argument is least applicable to soccer, and most applicable to basketball). The intuitive answer would seem to be .5, with the argument being that if team A happens to be ahead by 5 points at the end of the first half (i.e., they “win” ...

Discrete probability - Department of Computer Science
... Suppose that we flip a coin three times, and all eight possibilities are equally likely. Moreover, suppose we know that the event F, that the first flip comes up tails, occurs. Given this information, what is the probability of the event E, that an odd number of tails appears? Because the first flip ...

If E is an event that may happen when an experiment is performed, then the empirical probability of event E is P(E) ≈ ...
