Sofie claims to be a tasting expert. To test her abilities, someone bakes Sofie a cake using 3 of the following
 ingredients:
 Coffee Vanilla
 Nutmeg Cinnamon
 Sea salt
 Ginger
 Sofie's challenge is to identify which set of 3 ingredients was used in the cake. Suppose that Sofie is just
 randomly guessing.
 What is the probability that Sofie correctly identifies the set of 3 ingredients in the cake?
