- Breonna has purchased the life insurance policy for her fish for the price of $100 per year and Breonna will receive $4000 in case if her fish passes away. The insurance company estimated the probability of her fish passing away during the length of the policy to be 0.5%. Let XX be the insurance company's profit. Answer the following questions: 1. Create the probability distribution table for XX : XX outcome profit xx ,$ P(X=x)P(X=x) fish passes away fish survives 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 plWhich of the following best describes the concept of marginal probability? It is a measure of the likelihood that a particular event will occur, regardless of whether another event occurs. It is a measure of the likelihood that a particular event will occur, given that another event has already occurred. It is a measure of the likelihood of the simultaneous occurrence of two or more events. None of the above.statistics and probability Assume that there are 4 white, 2 black and 3 red balls in a bowl.

- 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.Please helpAiyana has purchased the life insurance policy for her snake for the price of $100 per year and Aiyana will receive $5000 in case if her snake passes away.
