WebDefinition of intersection. The intersection of a set A with a B is the set of elements that are in both set A and B. The intersection is denoted as A ∩ B. For example, if A is the set { ♢, ♡, ♣, ♠ } and B is the set { , ♡, ♠ }, then A ∩ B = { ♡, ♠ }. Or if I 1 is the interval [ 0, 2] and I 2 is the interval [ 1, 3], then I ... WebThe intersection of A and B, denoted by A ∩ B, is the set of all things that are members of both A and B. If A ∩ B = ∅, then A and B are said to be disjoint. Examples: {1, 2} ∩ {1, 2} = {1, 2}. {1, 2} ∩ {2, 3} = {2}. Some basic properties of intersections: A ∩ B = B ∩ A. A ∩ (B ∩ C) = (A ∩ B) ∩ C. A ∩ B ⊆ A. A ∩ A = A. A ∩ ∅ = ∅. WebDec 12, 2024 · The intersection of two sets A and B is defined as the set of elements that belongs to both the sets A and B. The symbol ∩ is used to represent the intersection of two sets. The formula for union of A and B two sets is A ∪ B = { x: x ∈ A or x ∈ B }. The formula for intersection of A and B two sets is A ∩ B = { x: x ∈ A and x ∈ B }. thick batter for frying
