- Flaws in a certain type of drapery material appear on the average of 3 in 100 square feet. If we assume a Poisson distribution, find the probability of at most one flaw appearing in 250 square feet.arrow_forwardThe probability that a company’s workforce has no accidents in a given month is 0.9. The numbers of accidents from month to month are independent. What is the probability that the third month in a year is the first month that at least one accident occurs? What is the probability that the fourth month in a year is the second month that at least one accident occurs?arrow_forwardThere are 9 chips in a ball. 3 of them have number 1, 2 of them have number 2, and the rest has number 3. If one chip is selected at random, and the number X (X is either 1, 2 ,or 3) is recorded, what is the expected value of X? what is the variance of X?arrow_forward
- For each question on a multiple-choice test, there are four possible answers, of which exactly one is correct. If a student selects answers at random, give the probability that the first question answered correctly is question 3.arrow_forwardCustomers arrive at a travel agency at a mean rate of 9 per hour. Assuming that the number of arrivals per hour has a Poisson distribution, give the probability that at least two customers arrive in a given hour.arrow_forwardWhen a customer buys a product at a supermarket, there is a concern about the item being underweight. Suppose there are 20 “one-pound” packages of frozen ground turkey on display and three of them are underweight. A consumer group buys five of the 20 packages at random. What is the probability that at least one of the five is underweight?arrow_forward
- A pair of dice is rolled and X is the random variable defined as the absolute value of the difference of the numbers of dots facing up on two dice. What is the expected value of X? What is the variance of X?arrow_forward77% of youth now have insurance due to the health care law. Let X equal the number of American youth in a random sample of n = 18 with private health insurance. What is the mean of X? What is the variance of X?arrow_forwardI need detailed help solving this exercise from homework of Calculus I.I do not really understand how to do, please do it step by step, not that long but clear.
