price, variable cost, and the annual sales volume. The product has a life of only one year. The
management has the data on these three factors as under:
Selling
Price(Rs.)
Probability Variable
Cost (Rs.)
Probability Sales
Volume(Units)
Probability
3 0.2 1 0.3 2,000 0.3
4 0.5 2 0.6 3,000 0.3
5 0.3 3 0.1 5,000 0.4
