answered | Why is this reasoning for the problem “What is the probability of picking a second ace after already picking one?” wrong? |

Time required to reach the goal when an object will be slowing down incrementally based on distance travelled? Note this text in the question: "After reaching a predefined minimum speed (10 km/h), it will keep its velocity constant (and it will need exactly one additional hour to reach the target)." |

Prove that for $x>1$ there exists $n\in\mathbb N\colon y < x^n$. You may want to provide your own thoughts on the problem before anyone comments on it. |

Probablity of network flow What do you mean by "P(edge a intersects edge b) = .75" -- do you mean probability that flow occurs on these is dependent (otherwise should be $.9 \cdot .8 = .72$? |

Itô Integral has expectation zero @hulik If you consider any SDE, e.g. $X_t = \mu(t,X_t) dt + \sigma(t,X_t) dB_t$ for some Brownian motion $B_t$, $\mu$ is called drift and $\sigma$ is called volatility. Since $M_t$ is a local martingale, $fdM$ has no drift, but drift is the only thing contributing to the expected value of the difference... |

How to convert up/down votes into a single number? would be much more preferable to use not just the expected value of the random variable in question, but also the standard deviation. |

Proof Help regarding Limit Differentiation The way it is phrased now, this is not true. Consider $f(x)=0 \forall x \in \mathbb{R}$, then $f'(a)=0 \forall a \in \mathbb{R}$ but the difference quotient does not exist, so certainly it cannot be positive. |

The product of digits equal to the sum of digits I'd think if there is one, you could get other ones by rotating them? I.e. if 1234 is ok, then 4321 must be ok as well, no? Or am I misunderstanding something? |

The product of digits equal to the sum of digits Not sure what does this have to do with the number itself? You are just looking for 4 digits that summed or multiplied give the same result? |
