Source sentences:
text: Property 5 (all paths from any given node to its leaf nodes contain the same number of black nodes) is not threatened, because the new node N has two black leaf children, but because N is red, the paths through each of its children have the same number of black nodes as the path through the leaf it replaced, which was black, and so this property remains satisfied.
text: Property 5 (all paths from a node to its leaves contain the same number of black nodes) also remains satisfied, since all paths that went through G, P and N went through G before, and now they all go through P.
text: However, all paths through P now have one fewer black node than paths that do not pass through P, so property 5 (all paths from any given node to its leaf nodes contain the same number of black nodes) is still violated.
