PLEASE ANSWER ASAP!!!

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 16. a) The probability that the project will be completed in 6 months = 0 (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 26 months = (round your response to four decimal places). d) The probability that the project will be completed in 38 months = round your response to four decimal places). e) The due date that yields a 95% chance of completion = months (round your response to two decimal places)
