We assume that the table gives the possible demands and their probability on any day. Therefore, the expected demand (ED) is the sum of the following.

1500 (0.2) = 300

1200 (0.5) = 120

1600 (0.15) = 240

1400 (0.25) = 350

1600 (0.20) = 320

1000(0.06) =    60

1500 (0.04) =   60

               ED = 1450  

\ The production target should be 1450 + 145 =1595                                                                                                                                  Choice (A)
