A survey indicates that 30% of the people who earn less than $35000 per year are homeowners. If a sample of 10 people who earn less than $35000 per year is randomly selected, what is the probability that the number of home homeowners, who earn less than $35000, will be less than 3? Find the mean and standard deviation of random variable X, where X is the number of people who earn less than $35000 out of 10 selected.
