Autumn has purchased the insurance policy from an insurance company to cover the value of hers house in case if it gets destroyed due to a fire for the price of $1600 per year. Autumn's house is worth $370000 and the probability that fire destroys the house during the length of the policy is estimated to be 0.4%. Let XX be the insurance company's profit. Answer the following questions: 1. Create the probability distribution table for XX : XX outcome profit xx ,$ P(X=x)P(X=x) the house is destroyed the house survived 2. Use the probability distribution table to find the following: E[X]=μX=E[X]=μX= dollars. (Round the answer to 1 decimal place.) SD[X]=σX=SD[X]=σX= dollars. (Round the answer to 1 decimal place.)

Q1. Let X be the number of major storms in a particular state in a given year. The probability of having no major storms is 0.50, of one major storm is 0.30, of two major storms is 0.10, of three major storms is 0.08, and of four major storms is 0.02 (there have never been more than 4 major storms in this state in a given year). (a) Write down the probability distribution of X in table form, and also check to make sure it is a valid probability distribution and find the expected number of major storms in a given year, and the standard deviation of the number of storms in a given year. (b) Find the probability that there is at least 1 storm in a given year. (c) If there was more than 1 storm, find the probability that there were 3 storms.
