In probability theory the sample space also called sample description space or possibility space of an experiment or random trial is the set of all possible outcomes or results of that experiment.
Sample space in the study of. Either to get a head or a tail. Since the sample space contains every outcome that is possible it forms a set of everything that we can consider. In this set theory formulation of probability the sample space for a problem corresponds to an important set.
Common sample spaces. In an experiment or any random trial when we make a set of all the results or outcomes that are possible in that experiment or trial that set is said to be a sample space of that particular experiment. So the sample space becomes the universal set in use for a particular probability experiment. Rolling an ordinary six sided die is a familiar example of a random experiment an action for which all possible outcomes can be listed but for which the actual outcome on any given trial of the experiment cannot be predicted with certaintyin such a situation we wish to assign to each outcome such as rolling a two a number called the probability of the outcome.
If we represent head by h. Scroll down the page for examples and solutions. Sample spaces abound and are infinite in number. Compound sample spaces statistics and probability 7th grade khan academy duration.
Sample space is a term associated with probability theory. Using sample space to determine probability of flipping a coin and possible outcomes. A sample space is usually denoted using set notation and the possible ordered outcomes are listed as elements in the set. More lessons on probability in these lessons we will learn simple probability experiments outcomes sample space and probability of an event.
It is common to refer to a sample space by the labels s w or u for.

The following diagram shows how the sample space for an experiment can be represented by a list a table and a tree diagram.
