### Instruction: help me answer this question One die of red colour, one of white colour and one of blue colour are placed in a bag. One die is selected randomly and rolled, and its colour and the number on its uppermost face are noted. Describe the sample space., think step by step
### Assistant:  , The answer is Let 1, 2, 3, 4, 5 and 6 be the possible numbers when the die is thrown. Also, let the die of red colour be R, the die of white colour be W, and the die of blue colour be B. The total number of possible outcomes equals (6 × 3) = 18. Hence, the sample space of the event is S={(R,1),(R,2),(R,3),(R,4),(R,5),(R,6),(W,1),(W,2),(W,3),(W,4),(W,5),(W,6) (B,1),(B,2),(B,3),(B,4),(B,5),(B,6)}.
