that is indeed an impossible question to answer for many reasons. First of all, no one knows how long most plants can survive as most succulents haven't been kept long enough in cultivation to know... secondly, life in cultivation is so different than life in nature that two have almost nothing to do with each other...
If something is a mammal, then it is a bat .. The converse is actually the contrapositive of the inverse and so always has the same truth value as the inverse, which is not necessarily the same as that of the original proposition. 1  Negation : .
1 For example, the theorem that all angles in a rectangle are right angles has as corollary that all angles in a square (a special case of a rectangle) are right angles. 2  A converse of a theorem is a statement formed by interchanging what is given in a theorem and what is to be proved. For example, the converse to the theorem that two right angles are equal angles is the statement that two equal angles must be right angles, and this is clearly not always the case. 2  A generalization is a theorem which includes a previously proven theorem as a special case and hence as a corollary.
