using markov chains to solve a project-euler problem? some hints who are trying to solve this problem: if only ten players are involved, the expected plays required rounded to ten significant digits is 40.56192661 |

Solving $a_1x^{4999} + a_2x^{4998} + a_3x^{4007}+…+a_{5000}x^{0}=n$ of course it is from not-so-friendly geometric-like sequence and I solved it using WolframAlpha trial and verified it myself using binary search. And it turns out that solving the equation this way was wrong for this kind of problem. |

if multiple dice are thrown, how can I calculate their variance and mean? surely it has to fair dice... |

simple probability and coin flip thank you. It wasn't obvious for me when I started thinking about this, but after your explanation it is crystal clear. It is used to solve this: projecteuler.net/problem=323 |

Proving the existence of a non-decreasing sequence What do you mean by one example of ${b_n}$ ? judging from the question, isn't my trivial $a_n$ a sequence of positive number whose sum converges? |

Proving the existence of a non-decreasing sequence if $a=2$, I think it is the solution you're looking for.. |

simple probability and coin flip 1) if you get 0 heads, flip again. 2) number of round. 3) we can't go over, since we're flipping (3-s) coins. |

Use the ratio test to determine if the infinite series $\displaystyle \frac{3^n}{2^n +1}$ converges or diverges. latex is really hard! |
