marriage probability problem hmm, but I don't have the exact number for seats. I'm inserting B first and then inserting D into holes between 2n-2 and 2n-1 people. Well.. then what did you get? |

marriage probability problem If A and B already sit next to each other, then treat A and B as an entity. Insert D into 2n -1 places, the probability that D is next to C is 2 / 2n-1... What did you get? |

marriage probability problem sorry, is it 2/ (2n-1)*n ? I used conditional probability |

expectation and variance problem hey, is E[x1] = 1/n and E[x1 x2] = 2/ 2n-1? |

Differential equation variation of parametres also, if I find two special solutions to the homogeneous solution, how can I get general solution to homogeneous one? Can I simply add c1, c2? |

Differential equation variation of parametres well, then n = -2 or n = -4, why is n = 2 also a solution? |
