Use the binomial formula to find the probability that exactly 2 hurricanes occur in the next 10 years. P(2) = (c) Use the Poisson formula to find the probability that at least 2 hurricanes occur in the next 5 years: P(x) = (a t) e-it x! P (22) =
Suppose the random variable X is the number of tails until a head comes up in the experiment of tossing a coin. The PMF of X is given by: X px(x) = ¹14(³4) * {0,1,2,...}(X). a) Show that this is indeed a valid PMF. b) Derive the CDF of X.
Engineering company has a task of checking compressive strength for 100 concrete cubes. The results revealed that 85 cubes passed the compressive strength test successfully and 15 cubes failed in the test. If 10 cubes are selected at random to be inspected by the company, determine the probability that the 8 cubes will pass the test and 2 cubes will fail in the test by using the Combinatorial Analysis. 0.4522 0.3415 0.6553 0,1156 O 0.2919

Each of 14 refrigerators of a certain type has been returned to a distributor because of an audible, high-pitched, oscillating noise when the refrigerators are running. Suppose that 9 of these refrigerators have a defective compressor and the other 5 have less serious problems. If the refrigerators are examined in random order, let X be the number among the first 6 examined that have a defective compressor. (a) Calculate P(X 4) and P(X < 4). (Round your answers to four decimal places.) P(X = 4) .4196 P(X < 4) 5944 (b) Determine the probability that X exceeds its mean value by more than 1 standard deviation.
