Given the project information in the following table, what is the probability of completing the National Holiday Toy project in $99-$time units? Hint: Use the $=$NORM.S$.$DIST$($z$,$ TRUE$)$ function in Excel to compute the probability. $($Carry at least $2$ decimal places in your task time and variance calculations and at least $3$ decimal places in your $z$ value calculation. Enter your final probability answer to $3$ decimal places.$)$
