o. The expected completion time for each path and its variance: (Round intermediate calculations to 4 decimal places and final onswers to 2 decimal places.) 0. The expected completion time for each path and its variance. (Round intermediate calculations to 4 decimal places and final answers to 2 decimal places.) Answer is complete but not entirely correct. The following precedence diagram reflects three time estimates for each activity. Determine: Use Table B1 and Table B2. b. The probability that the project will require more than 49 weeks. (Round intermediate colculotions ond final onswer to 4 decimal places.) c. The probability that the project can be completedin 46 weeks or less. (Round intermediate colculations and final answer to 4 decimal ploces.)
