$[10]$

The baseline time estimate for the completion of a mall construction project is in Middelburg is $28$ weeks and the baseline cost estimate is R$72000.$Assume that the risk likelihood for the project is $0\mathrm{.}3$ and if the risk is materialized $,$the project would be delayed by $7$ weeks and cost R $10000$ more.
