Final answer:
The set of all points two or more geometric figures have in common is called their intersection. It represents the shared elements between the sets. The intersection is often visualized in geometry where it shows the common area between overlapping figures.
Step-by-step explanation:
The set of all points two or more geometric figures have in common is called their intersection. This concept is part of set theory, which is often taught in mathematics, particularly geometry. When we talk about the intersection of two sets, we mean the elements that are common to both sets. If you were to visualize this with geometric figures, such as circles on a plane, their intersection would be the area where the circles overlap.
On the other hand, the union of two sets includes all the elements that are in either set, whereas the complement typically refers to elements not in a set, but within a larger universal set. The symmetric difference includes elements that are in one set or the other, but not in both.
Analogous to this, in the context of probability, the set A AND B would be the intersection of sets A and B which includes only the outcomes present in both sets, and A OR B would be the union of sets A and B which includes any outcomes that are in either set.
