Whoever downvoted this, please explain. I'm not seeing the problem. More could have been said (that's always the case), but what exactly do you think is wrong or badly written? (more) |

A: Picking 20 different numbers, in the same draw $\;$ vs. $\;$ picking 10 different numbers, in 2 different draws. Does Pr (probability) of winning jackpot differ between 1. picking 20 different #s, for the same draw vs. 2. picking 10 different #s, for 2 different draws ? Yes. Consider the limiting case where there are only 20 possible choices. Playing all 20 numbers guarantees a win. Playing 10 out of 2... (more) |

A: Solely by eye, how can 16 year olds visually distinguish $\color{red}{\vec{b} - \vec{r}}$ from $\color{limegreen}{|\vec{b}| - |\vec{r}|}$ ? Use two diagrams. What you have is too cluttered and busy to be useful. I had to look at it a while before understanding what you are trying to show. What you are really trying to illustrate is the difference between how vectors and scalars subtract. Show one diagram for the difference between ... (more) |

A: How can I choose a point from a uniform distribution within a regular polygon? Any convex polygon can be trivially tiled into triangles. Choose any point on the boundary or inside the polygon and draw lines from there to all the vertices. This point can be one of the vertices. It can also be the origin in your case. It doesn't matter what point is picked. Find the area o... (more) |

A: Without trial and error, how can I effortlessly deduce all $n, k_i ∈ ℕ ∋ \binom n {k_1, k_2, ..., k_n} =$ given c? I prefer to pick integers ≥32 to boost my probability of winning That's silly. All combinations of numbers have the same chance of winning. <Soapbox> You've asked a bunch of questions here that indicate you are trying to find a scheme to win the lottery. There isn't one. On...

Criteria for solvable Minesweeper game? Minesweeper is a computer game that works on a rectangular grid of squares. Initially, all the squares are shown blank. A known number of "mines" are distributed under the squares, but their locations are unknown to the player. The object of the game is to uncover all the squares by flagging each ... (more) |

Yes, and that seems rather strange, but the law is sometimes unintuitive. If I buy some arbitrary item for 5 dollars and you immediately take it from me, it seems a reasonable argument that you deprived me of 5d. If it was an ice cream cone and I let it sit and melt and you took the remains an hour... (more) |

A: How can disabled users not be scorned for their disabilities? Good posts are good, and bad posts are bad. It doesn't really matter why they were written that way. Anyone that usually writes good posts is welcome here. Anyone that usually writes bad posts is not. Again, it doesn't matter why. The reason we don't like bad posts is because they degrade th...

@#36356 I agree that what you're saying is effectively the case, but only because the linear approximation is quite good for small numbers of tickets relative to the odds of winning. If each ticket is guaranteed to have a unique number, then it is truly linear. But then only a fixed number can be s... (more) |

A: How do I compare lotteries' chances of winning jackpot, when they differ in the maximum number of plays? Do the odds below factor in each lottery's different maximum (number of) plays? Or are these odds calculated for merely 1 play? You'd have to ask each lottery, but usually such published odds are the chance of any one ticket winning. That appears to be the case here too. Does each lottery's di... (more) |

Yes you do. When you ask *here*, information pertinent to the question needs to be *here*. Links can be used for background information, but any question here needs to be understandable and answerable without following links. This question was correctly closed as *unclear* since you didn't define ... (more) |

This question makes no sense since you don't define what your expectations are of "d". If A changes to B, then there certainly is a value D where A + D = B. You seem to have some expectations about D, but since you didn't state them, your premise in the question is false. -1 since this should have ... (more) |

A: At what jackpot minimum is playing Lottario rational? This can't be answered with the information shown. -1 because that really should have been obvious. First, you need to know the cost of acquiring one of those 4,072,530 chances. For simplicity, you could say that's the price of a ticket. If the cost of entry were free, then the expected value o...

Since this Kaktovik numerals system is central to your question, you should include at least a brief introduction. Links should be for background and supporting information, not essential information. (more) |

A: Finding a quadratic that has solutions to given values If you only have one X-Y pair to meet, then a constant fits the specs perfectly: f(x) = K If it has to meet two X-Y pairs, then a line does it: f(x) = K1x + K2 A quadratic can hit three points: f(x) = K1x2 + K2x + K3 This is also known as a ...

A: How can 3/1 ≡ 1/(1/3), when left side features merely integers, but right side features a repetend? Your equations express rational numbers, and are correct. Just because in some numbering systems some of these rational numbers can't be represented with finite notation doesn't in any way invalidate the equations. (more) |

A: How to calculate remaining volume of a wire spool The relative volumes of cylinders with the same height are proportional to the square of their diameter. Hopefully you can see this is true without further explanation. The relative volume of wire on a full spool is therefore D2 - Dempty2 Now take the ratio of the current to ... (more) |
