Consider the following work breakdown structure:

$\backslash$table$[[,\backslash$table$[[$Start$],[$Activity$],[$Node$]],\backslash$table$[[$Finish$],[$Node$]],\backslash$table$[[$Duration $($days$)],[$Optimistic$]],$Most Likely,Pessimistic$],[$A$,1,2,41,50,59,,,],[$B$,1,3,54,60,66,,,],[$C$,2,4,58,70,82,,,],[$D$,3,4,32,41,44,,,]]$

What is the probability that this project will be completed within $130$ days?
