Find the indicated probabilities using the geometric distribution, the Poisson d

Question

Find the indicated probabilities using the geometric distribution, the Poisson distribution, or the binomial distribution. Then determine if the events are unusual. If convenient, use the appropriate probability table or technology to find the probabilities. A glass manufacturer finds that 1 in every 200 glass items produced is warped. Find the probability that (a) the first warped glass item is the 10th item produced, (b) the first warped item is the first, second, or third item produced, and (c) none of the first 10 glass items produced are defective. (a) P(the first warped glass item is the 10th item produced) = (Round to three decimal places as needed.) (b) P(the first warped item is the first, second, or third item produced) = (Round to three decimal places as needed.) (c) P(none of the first 10 glass items produced are defective) = (Round to three decimal places as needed.) Which of the events are unusual? Select all that apply. A. The event in part (a) is unusual. B. The event in part (b) is unusual. C. The event in part (c) is unusual. D. None of the events are unusual.

Explanation / Answer

a) P(First in 10th item produced) = 0.005

b) P(First in first, second or third item produced) = 0.015

c) P(None of the first 10 item produced are defective) = 0.951

d) Option A and Option B is correct.
