I can look at it, but it seems I can't undelete it (probably because you're the author deleting your own comment). What Matthew said was: $$\;$$ > Here's where my mind goes. Try a special case, say $P(m=2,M=5)$. What values can you not roll? What values must you roll at least one of? | |

| Sep 24, 2015 at 12:37 | comment | added | Antoni Parellada | @MatthewDrury Matthew, I am so sorry... It was a complete misunderstanding. I wasn't criticizing your comment. All the contrary, I was asking you for guidance as to whether to post an answer I had typed or not (which is what I ultimately opted to do) given the self-study nature of the post. Your hint was great! | |

| Sep 23, 2015 at 15:13 | comment | added | jlimahaverford | Can you write what $\frac{4}{6}^n$ equals in terms of $m, M$? If this is to hard can you give me an example of an event counted by $\frac{4}{6}^n$ which does not make $m=2, M=5.$ | |
| Sep 23, 2015 at 15:03 | comment | added | wikichung | @jlimahaverford It contains some situations which do not meet the condition $m=2$ and $M=5$. Thanks for your reminding. | |
| Sep 23, 2015 at 14:50 | comment | added | jlimahaverford | @wikichung $\frac{4}{6}^n$ is the probability of rolling between a $2$ and $5$, $n$ times in a row. If you do that, does that make $m=2$ and $M=5$? If not, what quantity is $\frac{4}{6}^n$, in terms of $m, M$? | |

| Sep 23, 2015 at 14:17 | comment | added | wikichung | @MatthewDrury, based on the correct answer, I reversely think about this question. My though was following: the probability $2=< x =< 5$ was $(\frac{4}{6})^n$. there was another situation only appeared 3 and 4 whose probability was $ (\frac{2}{6})^n$. The minus part in the answer suggest that this part was double counting. But I can not explain it. | |
| Sep 23, 2015 at 14:06 | comment | added | Matthew Drury | I didn't think of that as a full answer, just a "try to put your mind here". I will delete. My apologies. | |
| Sep 23, 2015 at 14:04 | comment | added | Antoni Parellada | @MatthewDrury Uncool to post a possible answer because of the self-study tag? | |
