Dear student
The two quantifiers are (i) There exist and For all

A statement with quantifier “ There exists ‘ is true, if it is true  for at least one case.

A statement with quantifier “ For all is true  if its true  for at least one case.

direct method , contrapositive method , method of contradiction and use of counter example are the ways of validating statements pls watch our video validating statements to understand them.

If you have any further problem then pls write to us.
