Are you sure it was the same question?
Firstly, the other reply seems to refer only to the number 6, whereas the question that I answered required all the throws to be the same (could be all 1s, all 2s ...etc. not just all 6s).
Secondly, the other reply seems to be calculating the probability that the first roll is a 6 or the second roll is a 6 or the third roll is a 6, whereas the question I answered required the first throw and the second throw and the third throw to be the same.
Definitely not answering the same question!
