Made Easy Test Series: Binary Tree
The number of node in each left subtree is within a factor of $2.$ of the number of nodes in the corresponding right subtree. Also a node allowed to have only one child if that child has no children. This tree has worst case height $O(logn)$. $N$ is the number of nodes in the binary tree. Is this statement TRUE about Binary Tree?

Let $T$ be a full binary tree with $8$ leaves. (A full binary tree has every level full.) Suppose two leaves $a$ and $b$ of $T$ are chosen uniformly and independently at random. The expected value of the distance between $a$ and $b$ in $T$ (ie., the number of edges in the unique path between $a$ and $b$) is (rounded off to $2$ decimal places) _________.
