My theory ... You are a paleontologist who finds part of a dinosaur bone. After careful study you determine there’s a 50% chance the dinos aur was a Juliasaurus, a 15% chance it was a Noahsaurus, and a 35% chance it is a new dinosaur altogether. Later your graduate student finds a confirmed Maxxasaurus bone at the same site. You know from earlier research that of all confirmed discoveries of Juliasaurus bones, 5% have been found at sites that also contain Maxxasaurus bones. Of all confirmed discoveries of Noahsaurus bones, 30% have been found at sites containing Maxxasaurus bones. And among all discoveries that are neither Juliasaurus or Noahsaurus, 10% have been found at sites containing Maxxasaurus bones. Imagine you have 1000 identical bone specimens. Complete the table below to help you decide which dinosaur is the most likely source of your original discovery.

- The following problem submitted by Daniel Hahn of Blairstown, Iowa, appeared in the Ask Marilyn column of Parade magazine. Source: Parade magazine. You discover two booths at a carnival. Each is tended by an honest man with a pair of covered coin shakers. In each shaker is a single coin, and you are allowed to bet upon the chance that both coins in that booths shakers are heads after the man in the booth shakes them, does an inspection, and can tell you that at least one of the shakers contains a head. The difference is that the man in the first booth always looks inside both of his shakers, whereas the man in the second booth looks inside only one of the shakers. Where will you stand the best chance?arrow_forwardAnother friend asks you to explain how to tell whether two events are dependent or independent. How would you reply? Use your own words.arrow_forward
