I lost six marks on a test because of this. Is it because it negates the restrictions that the denominators carry? or is it some rule created by mathematicians/my teacher?

If A and B are subsets of a metric space (X, d), the distance between them, d(A,B), is defined as d(A, B) = infimum {d(a, b) | a is in A, b is in B}. Show that:

a) If the closures of A and B intersect, then d(A,B) = 0. Is the converse true?

b) If A is compact, B is closed and A and B are disjoint, then d(A,B) > 0. If, instead of assuming A is compact, we just assume it's closed, then is it still true that d(A,B) > 0?

Thank you

When we do an experiment, we get lots of numbers and normally we use arithmetic mean to deal with them. But why don't we use geometric mean or harmonic mean?
