Math Expert that can solve question like below: NEED THE PERSON IN 8 HOURS 8. The number of hurricanes hitting the coast of Florida annually has a Poisson distribution with a mean of 0.8. ( a) What is the probability that more than two hurricanes will hit the Florida coast in a year? ( b) What is the probability that exactly one hurricane will hit the coast of Florida in a year? 9. Arrivals at a bank teller’s drive- through window are Poisson- distributed at the rate of 1.5 per minute. ( a) What is the probability of zero arrivals in the next minute? ( b) What is the probability of zero arrivals in the next 2 minutes? 20. Suppose that a Die- Hardly- Ever battery has an exponential time- to- failure distribution with a mean of 48 months. At 60 months, the battery is still operating. ( a) What is the probability that this battery is going to die in the next 12 months? ( b) What is the probability that the battery dies in an odd year of its life? ( c) If the battery is operating at 60 months, compute the expected additional months of life. 25. The time intervals between hits on a web page from remote computers are exponentially distributed, with a mean of 15 seconds. Find the probability that the third hit connection occurs after 30 seconds have elapsed.
