1. A retail business will take one of the products X, Y, and Z to market. Whichever product is chosen, the estimated returns vary according to the increase and decrease in demand. The probability of increasing demand for all options is 0. If the X product is selected and the demand increases, a return of 90.000 TL is expected, if it decreases, a loss of 10.000 TL is expected. If product Y is chosen and demand increases, a 60.000 TL return is expected, if it decreases, a 10.000 TL return is expected. If product Z is selected and demand increases, a 150.000 TL return is expected, if it decreases, a 35.000 TL loss is expected.
