Some parts of California are particularly earthquake-prone Suppose that in one metropolitan area, 30% of al homeowners are insured against earthquake damage Four at random. Let X denote the number among the four who have earthquake insurance. homeowners are to be selected (a) Find the probability distribution of x. (Hint: Let S denote a homeowner that has insurance and Fone who does not. Then one possible outcome is SPSS, with probability (0.30)(0.720.30) (0.30) and associated X value 3. There are 15 other outcomes.) (Round your answers to four decimal places) P(X) (b) Draw the corresponding probability histogram, Probability 14- 02 1 4 04 0.3 0.1 0.0 O Probability 0.4 0.3 0.2 0.1 0.0 0 3 1 2 3 (c) What is the mast isely value for A 4 4 Number with earthquake insurance Number with earthquake insurance Probability 0.4 0.3 0.2 0.1 0.0 O 0 1 2 3 4 Probability 0.4 03 02 0.1 00 Number with earthquake Insurance Number with earthquake insurance (d) What is the probabdity that at least two of the four sected have earthquake insurance?
