Question
100%
Some parts of California are particularly earthquake-prone. Suppose that in one metropolitan area, 26% of all homeowners are insured against earthquake damage. Four homeowners are to be selected at random. Let X denote the number among the four who have earthquake insurance.
(a) Find the probability distribution of X. [Hint: Let S denote a homeowner that has insurance and F one who does not. Then one possible outcome is SFSS, with probability (0.26) (0.74)(0.26) (0.26) and associated X value 3. There are 15 other outcomes.] (Round your answers to four decimal
places.)
