[計量] 問一題 感覺有點難
題目
Two cubical dice each have removable numbers 1 through 6. The tweleve
numbers on the two dice are removed, put into a bag, then drawn one at
a time and randomly reattached to the faces of the cubes, one number to
each face. The dice are then rolled and the numbers on the two top faces
are added. What is the probability that the sum is 7?
排列組合好難喔~ 可是機考會出那麼難的嗎
