| Question | — |
Without trial and error, how can I effortlessly deduce all $n, k_i ∈ ℕ ∋ \binom n {k_1, k_2, ..., k_n} =$ given c? With online or computer software, for a given $c ∈ ℕ $, how can I efficiently deduce all natural numbers that $n, ki ∈ ℕ[]() ∋ \dbinom n { k1, k2, \ldots , ki} = c$ ? For example below, $i = 1, \color{limegreen}{c = 4,072,530}$. Rule out trial and error! Context >You get two sets of six number... (more) |

| Question | — |
How to decide whether to buy a lottery with a too negative EV, but passable $\Pr($you win jackpot at least once│n plays)? Daily Keno's too negative Expected Value looks scammy. As many play the same lottery repeatedly, I shall consider $\Pr($ you win jackpot at least once│n plays) $= 1 - (1 - p)^n$. But some rational players can sensibly tolerate Keno's fairish $\Pr($ you win jackpot at least once │n plays). Be... (more) |

| Question | — |
Why do the Expected Values differ, for different wagers of the same lottery? For all the different wagers of Daily Keno's $10 PICK, the odds of winning jackpot are alike : 1 in 2,147,181. Then I calculated their EV. | Wager | Jackpot | EV $= [(Jackpot - Wager) \times Probability] - Wager$ | |:-:|:-:|:-:| | $10 | $2.5m | $\frac{2.5E6 - 10}{2147181} - 10 = -8.84$ ... (more) |

| Question | — |
How to compare lotteries, when one has highest probability of winning the jackpot, but another the highest Expected Value? Postulate that I shall always pick the lump sum for Daily Grand. The data below showcases that Pr(Keno's jackpot) > Pr(Grand's jackpot) > Pr(Lotto 649's jackpot). $\color{red}{\text{This probability inequality tips you to buy Keno!}}$ But the Expected Values of 1 Lotto 649 play= $= \dfrac{$5E...

Thanks. As you wrote "I may be misreading your post, but it seems like there is some confusion between these two things:", I edited my post. Does my edit clarify? Does my edit change your answer? (more) |

Thanks for your answer. $\color{magenta}{1.}$ I can't answer your first question, because I'm too dumbfounded by "P(you win the lottery exactly zero times | you won the lottery once)". Isn't this logically impossible??? Given that you won the lottery once, it's impossible that you win the lottery zer... (more) |

| Question | — |
How to intuit P(win the same lottery twice) $= p^{2}$ vs. P(win the same lottery twice | you won the lottery once) $= p$? Each lottery draw is independent, with probability $0 “If someone already wins the lottery, then the chance that the person wins the lottery a second time will be exactly the same as the probability they win the lottery if they had not previously won the lottery before,” Harvard statistics professor ...

How can disabled users not be scorned for their disabilities? My mental and physical disabilities (like Memory Disorder) appear to have unnerved some people, and been misconstrued. I apologize. I shall try to improve. But how can I convey my disabilities, so that I am not loathed? Does Codidact offer disability accommodations? Does Codidact want disable... (more) |

| Question | — |
Why does $ sometimes render as dollar sign successfully, but other times require escaping? I used solely `$` to write the dollar sign at https://math.codidact.com/posts/288038. As you can see, the `$` rendered the dollar sign perfectly under the heading GOLD BALL DRAW. But under GOLD BALL JACKPOT DRAW, some `$` failed to render as a dollar sign, while some $ did. On the same post,... (more) |

| Question | — |
What's mathematically fallacious with Edvin Hiltner's Lotterycodex patterns, to maximize your chance of winning lotteries? I distrust Edvin Hiltner's guidance, but for skepticism unrelated to math. 1. This website is asking for payment in USD for its "patterns". Buyer beware! A fool and his money are soon parted. If this alleged gambit worked, then 2. many more lottery players would tout it. Lotteries would foil i... (more) |
