As far as i Know, just one.
Do you know any formula to calculate how many binary search trees are possible?
--
answer:
(2n C n) / (n+1) = ( factorial (2n) / factorial (n) * factorial (2n - n) ) / ( n + 1 )
where 'n' is number of element (integer/string)
like:
N Number of BST
1 1
2 2
3 5
4 14
5 42
6 132
and so on

for 1 nodes it is 1.
For 2 distinct nodes it is 4.
For 3 nodes, using combinationaries it is 3*(4+4+2)=30
For 4 nodes it is 4 *(30*2+2*(4*1))=272(required answer)
Here answer is for creating any binary tree with no imposed restriction upon it.
Another answer: Not allowing empty trees, it is four or less. (Allowing empty trees it is infinite.)

Come on think, if this is too hard for you think about changing your courses.

Methods for storing binary trees?
Nodes, references and arrays are the methods for storing binary trees. It can also be stored in breath first order.
What is the difference between extended binary tree and a binary search tree?
A strictly binary tree is one where every node other than the leaves has exactly 2 child nodes. Such trees are also known as 2-trees or full binary trees. An extended binary tree is a tree that has been transformed into a full binary tree. This transformation is achieved by inserting special "external" nodes such that every "internal" node has exactly two children.
Number of all possible binary trees with 2 nodes is?
Two: 1. root and left child 2. root and right child
What can you tell as a conclusion to binary trees?
conclusion about binary tree
How would you describe the structure of a btree?
A binary tree can be empty, or consist of three parts: a 'value' (any type), and to binary trees, called as 'left child' and 'right child'
There are 8 15 13 14 nodes were there in 4 different trees Which of them could have formed a full binary tree?
In general: There are 2n-1 nodes in a full binary tree. By the method of elimination: Full binary trees contain odd number of nodes. So there cannot be full binary trees with 8 or 14 nodes, so rejected. With 13 nodes you can form a complete binary tree but not a full binary tree. So the correct answer is 15. niraj

What is the Number of possible binary trees with 3 nodes?
The number of branches is 8.
How many different binary trees and binary?
Infinite (and binary).
How many different trees are possible with 10 nodes?
1014 it is. no of different trees possible with n nodes is (2^n)-n thanx
Why you represent the general trees as binary trees?
General trees are not binary trees. It is the other way around, however, see the last paragraph for a different answer - explanation first... A binary tree is one with two possible child nodes, a left node and a right node, either of which might be not present. This particular representation implies a certain order between the node and its children, and if you walk the tree from bottom left to bottom right, you will traverse the nodes in order. A general tree is one with any number of possible child nodes, including no child nodes, so a binary tree is an example of a general tree, while a general tree is a generalization of a binary tree. However, in the general tree, the meaning of the child nodes might not have any specific ordering, like those in a binary tree, unless the general tree has other information contained in the node about order, because the concept of left and right has no implied meaning when there are more than two children. But, as promised, if the general tree has order, it is always possible to represent the general tree as a binary tree - there will just be more nodes, but they will only contain zero, one, or two children, and they will have an implied order.

What is the use of binary?
Binary trees are commonly used to implement binary search tree and binary heaps.
What can you tell as a conclusion to binary trees?
conclusion about binary tree
What is binary search in data structure using c?
a tree which has atmost two nodes is called binary tree binary search tree is a binary tree which satisfies the following 1.every node in tree must be distinct 2.values in right subtree > value at root 3.values in left subtree < value at root 4.left,right subtrees must be binary search trees
How would you describe the structure of a btree?
A binary tree can be empty, or consist of three parts: a 'value' (any type), and to binary trees, called as 'left child' and 'right child'
