Unformatted text preview: kets with probability 1/10. Let Ni be the number of customers that buy i tickets in the first hour. Find the joint distribution of (N1 , N2 , N3 ). 2.44. Ellen catches fish at times of a Poisson process with rate 2 per hour. 40% of the fish are salmon, while 60% of the fish are trout. What is the probability she will catch exactly 1 salmon and 2 trout if she fishes for 2.5 hours? 2.45. Signals are transmitted according to a Poisson process with rate . Each signal is successfully transmitted with probability p and lost with probability 1 p. The fates of di↵erent signals are independent. For t 0 let N1 (t) be the number of signals successfully transmitted and let N2 (t) be the number that are lost up to time t. (a) Find the distribution of (N1 (t), N2 (t)). (b) What is the distribution of L = the number of signals lost before the first one is successfully transmitted? 2.46. A policewoman on the evening shift writes a Poisson mean 6 number of tickets per hour. 2/3’s of these are for speeding and cost $100. 1/3’s of these are for DWI and cost $...
