1.4.1 Sample Space

To keep track of all the possible outcomes for a given random experiment, we use the concept of a sample space. The sample space is essentially the set of all possible outcomes that could occur for that experiment. It is generally denoted by  (Omega) or letter . Fig 1.9 shows the sample space for an experiment of rolling a die. Considering the six outcomes of the die, the sample space can be denoted as  = {1, 2, 3, 4, 5, 6}. To avoid any clutter, only two outcomes have been highlighted in Fig 9.
