2. Neha is doing a designing course. She is working on Cartesian
Art now a days. For it she wants to take x- coordinate from the set
A={0,1,2,3,5} and y- coordinate from the set B={-3,-2,-1,0,1,2,3}
(i)How many ordered pairs Neha can make from A to B?
(a)25 (b)30 (c)35 (d)40
(ii) How many ordered pairs Neha can make from B to A?
(a)25 (b)30 (c)35 (d)40
(iii) If a relation defined from A to B as R={(a,b):a<b ,a∈ A, b ∈ B}.Then how many elements are there in R
(a)6 (b)8 (c)12 (d)20
