Answer:
Sample Space = {(OSI), (OSH), (OEI), (OEH), (MSI), (MSH), (MEI), (MEH)}
Step-by-step explanation:
Given
Salad                               Meats                      Dressings
O = Olives                     S = Shrimp                 I = Italian  
M = Mushroom              E = Egg                     H = Honey mustard
To determine the sample space, we simply select one from each column.
Take for instance, a combination of Olives, Shrimp and Italian will be represented as: OSI
So, the following sample space exists:
Sample Space = {(OSI), (OSH), (OEI), (OEH), (MSI), (MSH), (MEI), (MEH)}
