Sample Space (1/3) A sample space is a list of all possible outcomes for a probability experiment. n(S) is the number of elements in the sample space. n(E) is the number of favourable elements in the sample space. Sometimes elements repeat and so we may be asked for distinct elements.

Sample Space Example 1 (2/3)
List the sample space of a barrel of marbles. 2 green, 1 blue and 3 red. S = {green, green, blue, red, red, red} Sample Space n(S) = 6 Number of elements Sample Space If E = {red, red, red} n(E) = 3 List of favourable Events Number of favourable elements
