Using PERT, Adam Munson was able to determine that the expected project completion time for the construction of a pleasure yacht is 22 months, and the project variance is 9 . a) The probability that the project will be completed in 13 months = (round your response to four decimal places). b) The probability that the project will be completed in 21 months = (round your response to four decimal places). c) The probability that the project will be completed in 25 months = (round your response to four decimal places)
