Answer:

{13}

Step-by-step explanation:

A ∩ B ∩ C = the set of all elements that are in sets A and B and C

This is indicated in the Venn diagram by the region that is common to all three circles which is the darkly shaded region. There is only one element that is included in this region and that is 13

In roster form we write it as {13}
