The minimum number of ordered pairs that need to be added to R to make (X, R) a lattice is _____.
Note: This question appeared as Numerical Answer Type.
Here in the given lattice a should be related as (a,a) , (a,b), (a,c), (a,d), (a,e) b: (b,c), (b,e), (b,b). c: (c,c), (c,e) d: (d,d), (d,e) e: (e,e) all pairs are already present here . Thus answer will be zero.
