2. In any given construction scenario a limited number of days can be taken out of the schedule before it to shorten the schedule further. Though it is impractical to take the exercise to the theoretical limit of sho theoretical limit that prevents any further shortening of the project. What defines this theoretical limit, an the schedule when this limit is reached?
Answer also given please show the work clearly. Note: kindly answer all otherwise leave it question. Thank you a What is the probability that path A-B-D-F-G will take from 100 to 120 days to complete? Answer = 40.2% b. What is the probability that path A-C-E-G will take less than 85 days to complete? Answer = 32.64% c. If the contract for the above project is 120 days, what is the chance of meeting the schedule? Answer = 86.3% d. What duration (number of full days) should be used to be at least 90% confident of finishing on time? Answer = 125 days - Probability of 93%
