Week 4 Homework (Graded Assignment)-Lauren LaTour 28. Find the indicated probabilities using the geometric distribution, the Poisson distribution, or the binomial distribution. Page 11 of 12 determine if the events are unusual. If convenient, use the appropriate probability table or probabilities Then technology to find the Assume the probability that you will make a sale on any given telephone call is 0.18. Find the probability that you (a) your first sale on the fifth call, (b) make your sale on the first, second, or third call, and (e) do not make a sale three calls. on the first (a) P(make your first sale on the fifth call)- (Round to three decimal places as needed.) (b) P(make your sale on the first, second, or third call)- (Round to three decimal places as needed.) (c) P(do not make a sale on the first three calls,- (Round to three decimal places as needed.) Which of the events are unusual? Select all that apply. The event in part (a), "make your first sale on the fifth call", is unusual. The event in part (b), "make your sale on the first, second, or third car, is unusual. The event in part (c), "do not make a sale on the first three calls. is unusual. None of the events are unusual. A. [ B. C. D. n the Poisson distribution, or the binomial distribution. Then

Explanation / Answer

a) Geometric Distribution problem.

To calculate the probability of a geometric distribution, use the geometric distribution function. Find this command by pressing 2ND [DISTR] and selecting geometpdf

geompdf(0.18, 5) = 0.08138

b) To calculate the cumulative probability of a geometric distribution, use the geometric cumulative distribution function. Find this command by pressing 2ND [DISTR] and selecting geometcdf

geometcdf(0.18, 3) = 0.4486

c) 1 - geometcdf(0.18, 3) = 0.5514

None of the events are unusual as all probabilities are greater than 0.05
