Only some statements have both examples and counter examples. A sufficiently clear and unambiguous statement would not have counter examples.
Counter-example
You figure it out!
A counter example is a statement that shows conjecture is false.
counter example
A counter example is a proof of a negation of a universal statement.A statement of the form "all X are Y" (e.g. all men are mortal), can be disproved by providing a counter example (here: something (someone) which is both a man and immortal).A more mathematical example of the use of a counter example could be to disprove the statement "the product of two prime numbers is odd". This is a claim about all numbers which are the product of two prime numbers (all elements in the set {n in N | n = p*q where p and q are prime numbers}). This set contains infinitely many pair numbers, but a single example (or witness), is enough to disprove the statement. Four is such a number and can serve as a counter example.
to find a counterexample
"All humans require food to survive" is an example of a universal statement, as it applies to every human being without exception.
The counter represents the amount of magic power he is using up. The counter starts at 9:9:9:9 and every time for example, gets into a fight, the counter drops.
binary form
A rectangle with dimensions of 1" x 2" .
s it counter-productive to change or update you personal mission statement?
Since the statement does not say that they have exactly two lines of symmetry, I do not believe that there is a counter example.
