Q6Numerical4 Marks26 Oct 2025Consider a set S={a∣a∈N, a≤10}S = \{a \mid a \in \mathbb{N},\, a \leq 10\}S={a∣a∈N,a≤10}. Let R1R_1R1 and R2R_2R2 be relations on S×SS \times SS×S defined as R1={(x,y)∣x,y∈S, y=3x}R_1 = \{(x, y) \mid x, y \in S,\, y = 3x\}R1={(x,y)∣x,y∈S,y=3x} and R2={(x,y)∣x,y∈S, y=x2}R_2 = \{(x, y) \mid x, y \in S,\, y = x^2\}R2={(x,y)∣x,y∈S,y=x2}. Find the cardinality of R1∖R2R_1 \setminus R_2R1∖R2.Your answerPress Enter to check.
