Answer:

Step-by-step explanation:

What you have are sets A and B and then the Union of those 2 sets.  The Union of sets is like the "marriage" of them.  The 2 sets come together and bring along with them ALL of their junk and they have to share it.

The upside down U indicates the intersection of the sets.  In other words, what they both have in common.  They both share a 5 and a 7.  Therefore, A∩B = {5, 7}
