Assume that the project completion time of a project follows Normal distribution. If the estimated time along the critical path of the project is $214$ days with the project variance of ${100}_{{?}_{?}}($The mean$/$average project completion time $=214$ days and the variance of the project completion time $=100).$

a$)$ What is the probability that the project will take $224$ days or more to complete?

b$)$ What is the probability that the project will take between $200$ to $230$ days to complete? Upload your work to HW$6$ folder.
