1 out of 8 dice is already know to be a six, so you have 7 unknown dice, each with a 5/6 chance of not rolling a six. can you figure it out with that information?

Note that your sample space will be such that there is always a throw in which you have got 6. so now keeping that in mind, simply calculate the probability. first find the probability that you didn't get any 6 after throwing a 6, this is the numerator and our denominator will contain (1  probability of not getting 6 in the any throws). You will get the answer.
