Answer the next $3$ questions using the following information: A project has three activities A$,$ B$,$ and C that must be carried out sequentially. The probability distributions of the times required to complete each of the activities A$,$ B$,$ and C are uniformly distributed in intervals $[1,5],[2,3]$ and $[3,6],$ respectively. Find the total project completion time and run $1000$ simulation trials in Excel.

Which of the following Excel functions would properly generate a random number for the duration of activity A in the project described above?
