They represent relationships between different sets.

It shows elements common to those sets.

The intersection of sets within the data.

It shows elements not in that set.

Union is noted as $A \cup B$.

Intersection is noted as $A ∩ B$.

It consists of three overlapping circles.

They show relationships between different events visually.

It's the probability of $A$ given that $B$ has occurred.

Using $P(A | B) = P(A \cap B) / P(B)$.
