How is a sample space different from a random variable?
A sample space is a collection of all possible outcomes of a random experiment. A random variable is a function defined on a sample space. We shall consider several examples shortly. Later on we shall introduce probability functions on the sample spaces. A sample space may be finite or infinite.
Which is an example of a sample space?
A sample space is the SET of values a random variable can take. You can think of random variable as an unopened box. This unopened box contains each member of the sample space with some probability. In your example of a dice roll, the sample space is {1,2,3,4,5,6}.
Which is an example of a random variable?
A random variable is a function defined on a sample space. We shall consider several examples shortly. Later on we shall introduce probability functions on the sample spaces. A sample space may be finite or infinite. Infinite sample spaces may be discrete or continuous. Tossing a coin.

How is a random variable defined in statistics?
What is Random Variable in Statistics? In probability, a real-valued function, defined over the sample space of a random experiment, is called a random variable. That is, the values of the random variable correspond to the outcomes of the random experiment. Random variables could be either discrete or continuous.
How many possible outcomes are in a sample space?
There are six possible outcomes and the sample space consists of six elements: {1, 2, 3, 4, 5, 6}. Many random variables may be associated with this experiment: the square of the outcome f (x) = x 2, with values from with the variable defined by f (x) = x – 3.5, etc. Drawing a card.
