'A particular type of wood has an average of 1.5 knots for every 10 cubic feet of (he wood_ Identify the type of distribution that describes this situation Find the probability that 10-cubic-foot volume has at most knot: Find the probability that 100 cubic feet of wood has exactly 15 knots. Is 15 knots the most likely number of knots we would observe in sample of 100 cubic feet? Explain.'

Suppose small aircraft arrive at an airport according to a Poisson process with rate $\lambda=8$ per hour, so that the number of arrivals during a time period of $t$ hours is a Poisson rv with parameter, $\mu=8 t .$ (a) What is the probability that exactly 6 small aircraft arrive during a 1 -h period? At least 6$?$ At least 10$?$ (b) What are the expected value and standard deviation of the number of small aircraft that arrive during a 90 -min period? (c) What is the probability that at least 20 small aircraft arrive during a 2.5 -h period? That at most 10 arrive during this period?
