Suppose X ∼ Poisson(2) and Y ∼ Poisson(1) are independent. ±ind Pr( X + Y ≤ 3). 5. At a nuclear plant, (minor) accidents occur to a Poisson process with a rate of one every two years. (a) What is the probability that the time between successive accidents is greater than two years? (b) What is the probability that 4 or more accidents will occur in a twoyear interval? (c) What is the mean number of accidents in ten years? (d) Suppose that a year has passed since the last accident. What is the probability that the next accident will occur at least three years from now? 6. [Will not be graded] Exercises 1, 2, 6, 7, 14, 19, 21, 30, 38, 39, 40, and 52 from Chapter 5 of BCN&N....
