Find 𝕆 intersect six, five, one, where 𝕆 is the set of odd numbers.
We can use a Venn diagram to help us think about this. Inside the yellow circle belong all odd numbers. Inside the pink circle is everything in our other set — six, five, and one. The part in the middle, the part where they overlap, would be any value that is included in the set six, five, one and is also odd like this.
The intersection is any values that fall within 𝕆 and in the specified set. In this case, the intersection is five and one.
