A resident of Boston spends the Summers in the Grand Tetons, Wyoming. Every day there is expectation that a moose may pass in front of the house. Moose are wild animals that live around that area. The daily sighting (number of times seen) of moose has the following probability mass function, where X is the daily number of sightings: x 0 1 2 P(X=X) 0.1 0.5 0.4 If this Boston resident spends 5 days in the Grand Tetons, how many moose are expected to be seen in total in the 5 days? There is uncertainty, of course, the true number seen in total could be different from the expected value. By how much will the total number of sightings depart from the expected value, on average?
