A ballet instructor is interested in knowing what percent of each year's class will continue on to the next, so that she can planwhat classes to offer. Over the years, she has established the following probability distribution.• Let X = the number of years a student will study ballet with the teacher.• Let P(x) = the probability that a student will study ballet x years.P(x)x*P(x)10.100.100.1040.300.200.05On average, how many years would you expect a child to study ballet with this teacher? (Enter an exact number as an integer,fraction, or decimal.)yr

Bill has purchased the insurance policy from an insurance company to cover the value of his new RV in case if it gets totaled for the price of $1300 per year. Bill's RV worth $38000 and the probability of him totaling the RV during the length of the policy is estimated to be 0.1%. Let X be the insurance company's profit. Answer the following questions: 1. Create the probability distribution table for X: X outcome profit x ,$ P(X=x) RV is totaled RV is not totaled 2. Use the probability distribution table to find the following: E[X]=μX= dollars. (Round the answer to 1 decimal place.) SD[X]=σX= dollars. (Round the answer to 1 decimal place.)
