A fair dice is being rolled. What is the probability that a six appears in at most n attempts?

i'm not sure, but i think it is the same probability as when the dice is being rolloed once (here's your hint!)

So the question is basically what's the probability of you rolling a 6 ?

or it might be n/6 (lol) but i think my first answer is better

Well, i feel the answer is {1-1/(6^n)}

[Sillysidley]

isn't 1-1=0

[Sillysidley]

and the probability is not 0

wa i right?
