Problem 3. Probability and Probability Distributions "a)The figure shows a box with 8 letters. Some letters are repeated. Suppose 4 letters are drawn at random from the box one-by-one without replacement. What is the probability of the outcome HULU, with the letters chosen in exactly the order given?" "b) The statistical analysis of the long-distance calls made from the headquarters of the Bricks and Clicks Computer Corporation indicates that the length of calls is normally distributed with = 228 seconds and = 37 seconds. What is the probability that a randomly selected call lasts: a) more than 205 seconds? b) no more than 184 second? c) exactly 192 seconds? d) between 183 and 298 seconds? e) at least 222 seconds? f) less than 195 seconds?"
