7. Describe the sample space for the indicated experiment.
One die of red colour, one of white colour and one of blue colour are placed in a bag. One die is selected at random and rolled, its colour and the number on its uppermost face is noted. Describe the sample space.
Let, R denote the event the red die comes out,
W denote the event the white die comes out,
B denote the event the Blue die is chosen
When a die is thrown, the possible outcomes are = {1, 2, 3 ,4 ,5 ,6}
The required sample space is:
S = {R1, R2, R3, R4, R5, R6, W1, W2, W3, W4, W5, W6, B1, B2, B3, B4, B5, B6}
