Using PERT, Adarn Munson was able to determine that the expected project completion time for the construction of a pleasure yacht is 21 months, arid the project variance is 9. a) The probabiify that the project will be cormpleted in 12 months = (round your response to four decima places). b) The probability that the project will be completed in 20 months = (round your response to four decimal places). c) The probabiuty that the project wi be completed in 24 months = (round your response to four decimal ploces). d) The probabity that the project wia be completed in 30 months = (round your response to four decimar places). e) The doe date that yields a 95% chance of completion = . months (round your response to ho decimal phices)
