Counterexample is an example that is used to disprove a statement,it proves that a statement is not ALWAYS true,but it can not prove a statement is NEVER true.
Here is an example:'The opposite of a number is always positive.'
Counterexample for the above statement:The opposite of 2 is - 2,a negative number.But as I said,this counterexample can not prove above statement is NEVER true - The opposite of -2 is 2,which is true.
请将问题重新输入一遍,不要复制.我检查一下错别字.
A justification that uses only counter examples should not convince you that a statement is never true.Say why.
一个仅用反例论证的证明 不足以证明一个命题是恒错误的。
比如,
如果要证明
“苹果是红色的”这个命题是恒错的(也就是说所有苹果都不是红的),如果你只找到一些青苹果,并不能说明其他苹果就不是红的了。
