A simple sequential project $($each task must be completed before the next one can begin$)$ has the time estimates $($in days$)$ shown below:

$\backslash$table$[[$Task$,\backslash$table$[[$Best$],[$Case$]],\backslash$table$[[$Most$],[$Likely$]],\backslash$table$[[$Worst$],[$Case$]],\backslash$table$[[$Expected$],[$Duration$]],\backslash$table$[[$Standard$],[$Deviation$]],\backslash$table$[[$Standard$],[$Deviation$],[$Squared$]]],[$A$,2,3,4,,,],[$B$,1,1\mathrm{.}5,2,,,],[$C$,\mathrm{.}5,1,1\mathrm{.}5,,,],[$D$,1\mathrm{.}5,2,2\mathrm{.}5,,,],[$E$,\mathrm{.}5,1,1\mathrm{.}5,,,],[$F$,\mathrm{.}4,\mathrm{.}5,\mathrm{.}6,,,]]$

What is the expected total time for the project?

A$.7\mathrm{.}33$ days

B$.9\mathrm{.}00$ days

C$.10$ days

D$.12\mathrm{.}67$ days
