A wiring diagram is a simplified conventional pictorial representation of an electrical circuit. It shows the components of the circuit as simplified shapes, and the power and signal connections between the devices.
A wiring diagram usually gives information about the relative position and arrangement of devices and terminals on the devices, to help in building or servicing the device. This is unlike a schematic diagram, where the arrangement of the components' interconnections on the diagram usually does not correspond to the components' physical locations in the finished device. A pictorial diagram would show more detail of the physical appearance, whereas a wiring diagram uses a more symbolic notation to emphasize interconnections over physical appearance.
A wiring diagram is often used to troubleshoot problems and to make sure that all the connections have been made and that everything is present.
Architectural wiring diagrams show the approximate locations and interconnections of receptacles, lighting, and permanent electrical services in a building. Interconnecting wire routes may be shown approximately, where particular receptacles or fixtures must be on a common circuit.
Wiring diagrams use standard symbols for wiring devices, usually different from those used on schematic diagrams. The electrical symbols not only show where something is to be installed, but also what type of device is being installed. For example, a surface ceiling light is shown by one symbol, a recessed ceiling light has a different symbol, and a surface fluorescent light has another symbol. Each type of switch has a different symbol and so do the various outlets. There are symbols that show the location of smoke detectors, the doorbell chime, and thermostat. On large projects symbols may be numbered to show, for example, the panel board and circuit to which the device connects, and also to identify which of several types of fixture are to be installed at that location.
A set of wiring diagrams may be required by the electrical inspection authority to approve connection of the residence to the public electrical supply system.
Wiring diagrams will also include panel schedules for circuit breaker panelboards, and riser diagrams for special services such as fire alarm or closed circuit television or other special services.

Tree diagrams display all the possible outcomes of an event. Each branch in a tree diagram represents a possible outcome. Tree diagrams can be used to find the number of possible outcomes and calculate the probability of possible outcomes.
Sometimes a visual aid is necessary to solve probability problems. This activity will teach students how to create diagrams.
Tree diagrams are particularly useful in probability since they record all possible outcomes in a clear and uncomplicated manner. First principles Let's take a couple of examples back to first principles and see if we can gain a deeper insight into tree diagrams and their use for calculating probabilities. Example:
What Is A Probability Tree Diagram. We can construct a probability tree diagram to help us solve some probability problems. A probability tree diagram shows all the possible events. The first event is represented by a dot. From the dot, branches are drawn to represent all possible outcomes of the event.
A decision tree is a decision support tool that uses a tree like model of decisions and their possible consequences, including chance event outcomes, resource costs, and utility.It is one way to display an algorithm that only contains conditional control statements.. Decision trees are commonly used in operations research, specifically in decision analysis, to help identify a strategy most ...
Tree Diagrams For Independent Events. Example: Julia spins 2 spinners; one of which is labeled 1, 2 and 3, and the other is labeled 4, 5 and 6. a) Draw a tree diagram for the experiment.
So, using the platonic solids we can have dice with 4, 6, 8, 12 or 20 faces! But with some imagination we can actually make fair dice with any number of faces we want. How about these interesting dice? Or this 10 sided one. Or this 20 sided Roman die that is 1,800 years old.
Tree diagrams are a visual way of showing all possible outcomes of two or more events. Each branch is a possible outcome and is labelled with a probability. Two events are independent if the ...
A decision tree is a flowchart like diagram that shows the various outcomes from a series of decisions. It can be used as a decision making tool, for research analysis, or for planning strategy. A primary advantage for using a decision tree is that it is easy to follow and understand.
Tree diagrams. Tree diagrams are a way of showing combinations of two or more events. Each branch is labelled at the end with its outcome and the probability. is written alongside the line.
