# Question: ESRF European Synchrotron Radiation Facility reports that its X ray equipment

ESRF (European Synchrotron Radiation Facility) reports that its X-ray equipment has an average failure rate of .02 failures per hour. Assume all Poisson conditions are met. Use the Poisson probability function to determine the probability of

a. Exactly one failure in a 10-hour period.

b. No more than one failure in a 120-hour period.

c. Exactly three failures in a 100-hour period.

d. No failures in 30-hour period.

Use the Poisson table to find the following probabilities: a. For λ = 2, P(x = 4) b. For λ = 6, P(x = 14) c. For λ = 3.5, P(x < 1) d. For λ = 2, P(3 < x < 5) You have just bought three stocks: Stock A, Stock B, and Stock C. Given the current market, you estimate that each stock has a 60% chance of doubling in value. Assume that stock performances are statistically independent. ...Use the Poisson table to approximate the following binomial probabilities: a. P(x = 2) when n = 50, p = .1 b. P(x = 5) when n = 300, p = .02 c. P(x = 1) when n = 500, p = .005 Demand for your company’s product is influenced by two factors: economic conditions for the year (good, fair or poor) and the intensity of market competition (intense or moderate).
