Symbоls fоr Relаtiоnаl Algebrа Expressions and Other Symbols Symbols for relation schemas: R, S, T Symbols for relations: R, S, T, ∅ Symbols for Relational Algebra operators: ∪, -, π, σ, ρ, ⨯, ∩, Δ, ÷, ⨝, ⟗, ⟕, ⟖, ⋉, ⋊, ▷ Symbols for logical connectives: ∧, ∨, ¬ Symbols for comparison predicates: , =, ≤, ≥, ≠ Symbols for set-theoretical operations: ∈, ∉, ⊆, ⊂, ⊇, ⊃ Other mathematical symbols: ⊥, ⋅, ∃, ∀, ∘, ←, → All names (for example, for relations and attributes) should be written in normal font (no italics) to increase readability. All symbols should be surrounded by blanks to increase readability. Let R(A, B, C), S(B, D), and T(A, C) be relations such that R has r tuples, S has s tuples, and T has t tuples with r > 0, s > 0, and t > 0. The attributes A, B, C, and D are supposed to have the same numerical data type. Consider the given Relational Algebra expressions below and determine the minimum number and the maximum number of possible tuples of each result relation. Explain your answers by using a clear argumentation, possibly a precise mathematical formulation, and not only colloquial language. [3 points] R ▷ S [3 points] R ⟕ S
