For two fair dice (one colored red and one colored blue), the chance of
Die-Blue coming up 1 and Die-Red coming up 6 is given by "1 out of 6"
times "1 out of 6" or 1/36 (approximately 0.028).
Note that Die-Red showing 1 and Die-Blue showing 6 is also a possible
outcome, in which case one would adjust the answer to 2 times 1/36 or
2/36 equal to 1/18 (approximately 0.056).
