a. Which project network is correct? (i) (III) (iv) b. Campute the expected duration and variance of each actwity. If required, round your answer to two detimals. If your answer is zero, enter "0". c. Decermine the critical path in the project network. d. What is the expected curation and variance of the critical path? If required, round your answer to two decimals. Expoctod durntion = Variance = e. Whet is the Fiselihood that the project will be completed within 30 days? If recuired, round pour anywer to four decimals. Mote: Use Anppendix B to identify the orobability. Likelihood = f. If activity B is dalayed by six days bepond its narly start time, how does this affect the axpacted project duration? if moquirad, round your answar to ana dacimal place. A delay of 6 days to uctivity B affect the time to complete this project because activity B has a slack of daps. For path B-D-F: z= Cumulative probability = For path AF : z= Cumulative probability = P( entire project completed )=
