Probability and the Law of Addition
... In the game Parcheesi, to take someone else's game piece you can use either die or the sum of both die. This means that the probabilities of various numbers are different than how they are usually calculated. Suppose you need to throw a 3. You can get a 3 with either die or with the sum of the die. ...

... Example: Spell-check software catches ”nonword errors” that result in a string of letters that is not a word, as when ”the” is typed as ”teh”. When undergraduates are asked to type a 250-word essay(without spell-checking), the number X of nonword errors has the following distribution: Value of X ...

... between each runner and the photographer (at the time of the picture) is constant on the interval [1, 6], measured in feet. (Assume that the locations of the runners are independent.) The photographer’s “very good” pictures are taken when the object is less than 3 feet away. What is the probability ...
