Final Answer:
The intersection of sets a, b, and c is the empty set, represented by {}. This is because there are no elements common to all three sets.
Step-by-step explanation:
The intersection of two sets A and B is the collection of elements that are in A and also in B. Similarly, the intersection of three sets A, B, and C is the collection of elements that are in A, and also in B, and also in C.
In this case, the sets a, b, and c do not share any common elements. Therefore, the intersection of all three sets is the empty set, which contains no elements.
