Tamara has 1000 orders of deli
=> 450 = ordered for turkey
=> 375 = ordered for ham
=> 250 = ordered for either ham and turkey
Now, let’s start calculating the possible answer:
=> 1000 – 250 (neither ham or turkey)
=> 750 remaining ham and turkey order
=> 450 ordered turkey and 375 ordered ham
=> 450 + 375 = 825 ordered for ham and turkey
=> 825 – 750 = 75
SO, it shows that there will be sure 75 ordered of neither ham nor turkey for
the next 1000 order.
