1. ## parallel world problem

1. Let us now try to analyse the chance of whale-sighting based on the given data in Whales.xls. Assume that a “whale-sighting” devil has chosen to sit beside you during the trip. The devil tosses a biasedcoin once every hour. If a HEAD shows up, you will encounter a whale-sighting. Conversely, if a TAIL shows up, you will not encounter a whale-sighting.
Use the ‘Parallel Worlds’ method to model the above situation for a 5-hour trip.

The fact that the only relevant hit with "parallel worlds method" on google is this thread suggests that your instructor has just invented this term and most people outside your school (or not using your text book) have no idea to what it refers.

If you can provide a link or description for "parallel worlds method" you will be more likely to get a sensible response.

3. Also, if it's a biased coin, isn't the result already pre-determined?
