Let `A={1,2,3,5,6}` and `B={1,6,7,8}`. Let R be a relation from A to B is defined as `R=((a,b):a>b,a in A and b in B}`.Then the number of elements in R is

Let A={1,2,3,4} and B={5,7,8,9} be two sets and the relation R from A to B be defined as R={(a,b)in A times B:|a-b| is an even number } .Then the number of elements in the relation R is

Let R be a relation on a set A = {1,2,3,4,5} defined as R = { (a,b) : | a ^(2) - b ^(2)| lt8}. Then the reation R is

Let A={1,2,3,5}" and "B={4,6,9}. Define a relation from A to B, given by R={(a,b):a inA,b inB" and "(a-b)" is odd"}. (i) Write R in roster form. (ii) Find dom (R) and range (R).

Let A={3,5,7},B={2,6,10} and R be a relation from A to B defined by R={(x,y):x and y are relatively prime. Then,write R and R^(-1)

Let A={1,2,3,4) and R be the relation on A defined by {(a,b):a, be A, a b is an even number }, then the range of R is

Let R be a relation defined by R = {(a, b) : a ge b }, where a and b are real numbers, then R is
