(1 point) Suppose that you randomly draw one card from a standard deck of 52 cards. After writing down which card was drawn, you replace the card, and draw another card. You repeat this process until you have drawn 15 cards in all. What is the probability of drawing at least 5 hearts? For the experiment above, let X denote the number of hearts that are drawn. For this random variable, find its expected value and standard deviation. E(X) = Give your answers to at least 4 decimal places.(1 point) The rates of on-time flights for commercial jets are continuously tracked by the U.S. Department of Transportation. Recently, Southwest Air had the best reate with 80 % of its flights arriving on time. A test is conducted by randomly selecting 19 Southwest flights and observing whether they arrive on time. (a) Find the probability that at least 4 flights arrive on time. (b) Would it be unusual for Southwest to have 5 flights arrive late? (Enter YES or NO) No Give your answer to at least 4 decimal places
