Answer

Let the dice of red colour, white colour and blue colour be denoted by R, W and B.
Faces of each die are marked 1, 2, 3, 4, 5 and 6.
$\therefore$ When a die is selected at random and rolled, then the sample space (S) of the experiment
is given by S= { R1, R2, R3, R4, R5, R6, W1, W2, W3, W4, W5, W6, B1, B2, B3, B4, B5, B6 }
