Given A = {4, 5, 6, 7}, B = {4, 6, 8} and a relation R from A to B such that: R = {(x,y):xϵA,yϵBandx≥y}. Find R.

Solution
For the required Relation we have to find the ordered pairs where x co-ordinate is from set A which is greater than or equal to the y co-ordinate
from set B. So, the relation is R={(4,4),(5,4),(6,4),(6,6),(7,4),(7,6)}.
