Answer» Answer: You have not STATED that A's die is 1-12 (on the FACES) and B's 1-20 and both are fair DICE. Obviously there is no HOPE of approaching this question if we know nothing about the dice. Or to be more accurate, the REASONING will be totally different. Please mark it as brainliest answer if you like the answer and follow me |
