Suppose we have the following activity list that includes information on immediate predecessors along activity completion times $($in weeks$)$ under optimistic, normal, and pessimistic scenarios:

Immediate

Activities Predecessor Optimistic Normal Pessimistic

A $---1711$

B $---3810$

C A$,$B $111$

Using this information and based solely on the critical path, what is the probability that this project will be completed in $10$ weeks or less?

Question $10$ options:

$0\mathrm{.}9015$

$0\mathrm{.}9546$

$0\mathrm{.}50$

$0\mathrm{.}8977$
