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 abiasedcoin 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.
