24 months and variance is 16

Using PERT, Adam Munson was able to determine that the expected project completion time for the construction or a pleasure yacht is 2 months and the project varianca *** a) The probability that the project will be completed in 6 months = round your response to four decimal place b) The probability that the project will be completed in 23 montaround your response to four decimal places c) The probability that the project will be completed in 28 months found your response to four decimal places) d) The probability that the project will be completed in 40 months-fround your response to four decimal placea). The due date that yields a 95% chance of completion montre pound your response to two decimal places)
