man is investigating the populaion of bear in two areas. Area 1 and Area 2. He expect the number of bear to be X and Y in area 1 and area 2 to be Poisson- distributeted.  If a bear is in one of his areas , there is an expected probability of 0.2 for the dear to be observed. If there are 5 dear in one of the areas what is the probability for 3 of them to be observed and what is expected dears observed
