If actuarial studies show the probability that any 42-year old man will die in a given year to be 0.001, find the exact probability that the company have to pay x=4 claims during a given year. 2. A case of softdrinks has 12 bottles, three of which contain less than what is labeled per bottle or underfilled. A sample of 4 bottles is selected from the case. a. Find the probability distribution for x (number of underfilled bottles) in the sample h What are the reson and variance of
