Answer»

Fix the number on D4. The probability of the event that D1 has a different number then the one on D4 is5/6, and this probability is same for D2 and D3.

Therefore the event in which D1 D2 D3 has a different number than the one on D4 has a probability(5/6)³=125/216

Hence the event that we are interested in has a probability1−125/216=91/216
