A coin is tossed. If it shows a tail, we draw a ball from a box which contains 2 red and 3 black balls. If it shows head, we throw a die, find the sample space for this experiment.

be R₁, R₂ for red ball or B₁, B₂, B₃ for black balls. If it is head then a die is thrown and it may show 1, 2, 3, 4, 5 or 6 number on the die. Here we denote the outcome of the experiment as TR, H1 and so on.

The sample space is given by:

S = {TR₁, TR₂, TB₁, TB₂, TB₃, H1, H2, H3, H4, H5, H6}
