"WebbBy property 2, any node with height h has black-height at least h/2. (At most half the nodes on a path to a leaf are red, and so at least half are black.) We can also show that the subtree rooted at any node x contains at least 2 bh(x) − 1 internal nodes. The proof is by induction on the height of x.The basis is when h(x) = 0, which means that x is a leaf, and … " - Simple example of red black tree
