udson Corporation is considering three options for managing its data processing operation: continuing with its own staff, hiring an outside vendor to do the managing $($referred to as outsourcing$),$ or using a combination of its own staff and an outside vendor. The cost of the operation depends on future demand. The annual cost of each option $($in thousands of dollars$)$ depends on demand as follows:

Demand

Staffing Options High Medium Low

Own staff $650650600$

Outside vendor $900600300$

Combination $800650500$

If the demand probabilities are $0\mathrm{.}2,0\mathrm{.}5,$ and $0\mathrm{.}3,$ which decision alternative will minimize the expected cost of the data processing operation?
