Tree diagram. v. t. e. In probability theory, a tree diagram may be used to represent a probability space . A tree diagram may represent a series of independent events (such as a set of coin flips) or conditional probabilities (such as drawing cards from a deck, without replacing the cards). [1] Each node on the diagram represents an event and ...
A tree structure, tree diagram, or tree model is a way of representing the hierarchical nature of a structure in a graphical form. It is named a "tree structure" because the classic representation resembles a tree, although the chart is generally upside down compared to a biological tree, with the "stem" at the top and the "leaves" at the ...
Bayes' theorem (alternatively Bayes' law or Bayes' rule, after Thomas Bayes) gives a mathematical rule for inverting conditional probabilities, allowing us to find the probability of a cause given its effect. [ 1] For example, if the risk of developing health problems is known to increase with age, Bayes' theorem allows the risk to an ...
v − 1. Chromatic number. 2 if v > 1. Table of graphs and parameters. In graph theory, a tree is an undirected graph in which any two vertices are connected by exactly one path, or equivalently a connected acyclic undirected graph. [ 1] A forest is an undirected graph in which any two vertices are connected by at most one path, or equivalently ...
A tree diagram is a connected forest diagram. An example of a tree diagram is the one where each of four external lines end on an X . Another is when three external lines end on an X , and the remaining half-line joins up with another X , and the remaining half-lines of this X run off to external lines.
Tree topology, a topology based on a hierarchy of nodes in a computer network. Tree diagram (physics), an acyclic Feynman diagram, pictorial representations of the mathematical expressions governing the behavior of subatomic particles. Outliners, a common software application that is used to generate tree diagrams. Network diagram.
In computer science, a tree is a widely used abstract data type that represents a hierarchical tree structure with a set of connected nodes. Each node in the tree can be connected to many children (depending on the type of tree), but must be connected to exactly one parent, [ 1] except for the root node, which has no parent (i.e., the root node ...
Tree (set theory) A branch (highlighted green) of a set-theoretic tree. Here dots represent elements, arrows represent the order relation, and ellipses and dashed arrows represent (possibly infinite) un-pictured elements and relationships. In set theory, a tree is a partially ordered set ( T , <) such that for each t ∈ T, the set { s ∈ T ...
