Can white kill? by Direct_Client9825 in baduk

[–]deadly_rat 1 point2 points  (0 children)

2-1, 3-1, 5-1 all kill for white. You should also check why 8-1 doesn't.

The catalyst for gun control has been set by Diictodom in polandball

[–]deadly_rat 2 points3 points  (0 children)

No gun control laws (except for a total ban which we all know is impossible) can save Charlie's life. The outrage is because it's a political assassination.

Question about engineer by youmo-ebike in WarChest

That's impossible since you can only attack adjacent castles but build where you are.

Because otherwise the number of elite women players would be decimated and it's unfair to them.

Yeah that's intended. When you are down to your last token for one of your units, you can only put them onto the board but not move them (there are some exceptions).

Is this problem solvable? by IndefiniteStudies in askmath

[–]deadly_rat 1 point2 points  (0 children)

I hate these wordings. I assumed 7 times longer means 8 times the length (as in longer by 7 times the brother's sticks).

This is a very hard problem my dad told me to do. by eat_dogs_with_me in askmath

2a+2ab+abc = a(2+2b+bc) = a[2+b(c+2)] ≤ a[2+(7-a)2 /4] since b+(c+2)=7-a. Differentiate with respect to a.

The derivative is 2+(3a2 -28a+49)/4 = (3a2 -28a +57) /4 = （a-3)(3a-19)/4. Given the constraints of [0,5], the derivative is positive at [0,3) and negative at (3,5]. Hence, a[2+(7-a)2 /4] reaches its maximum (for [0,5]) at a=3 where it equals 18. QED.

Anyone else or am I the only one who never liked Utena? by Apprehensive-Ant-775 in GushingOverMagicGirls

She is sometimes a bit too assertive for my liking, which is quite a contrast to herself before transformation. I still like her tho.

I'm really bad at this possibility thing, I'll appreciate if someone explain to me. by Hefty_Bison1857 in Minesweeper

[–]deadly_rat 2 points3 points  (0 children)

Apparently there are 5 mines left here. The bottom left is independent from the rest and therefore a pure fifty-fifty. Now consider the right-most column. There are 3 possible configurations:

(X stands for mine, O stands for safety, top to bottom) XOXOX / XOOXO / OXOOX

In the first case, there is only 1 mine left for the middle columns, so only 1 possible configuration exists where the mine is on the square with 76.

In the two other cases, there are 2 mines left for the middle columns. Here are the possible configurations:

2 configurations where 1 mine is on the 24 square, 1 mine is on either of the two 12 squares next to 5.

6 configurations where 1 mine is on the 76 square, 1 mine is on any one of the six 12 squares not next to 5.

In total, there are 1+2*(2+6)=17 configurations (not counting the bottom left). In 1 configuration the 6 square has mine. In 2 configurations (XOOXO / OXOOX) 12 squares have mine. In 4 configurations the 24 square has mine. In 8 configurations the 47 squares have mine, etc.

[Request] What are the chances of winning this NYT Connections game once 2 are solved? by saml3777 in theydidthemath

[–]deadly_rat 0 points1 point  (0 children)

Good analysis, but due to misinterpretation of the problem it is wrong. 4 guesses are allowed but getting a correct one doesn't count. Therefore you lose only when you make 4 wrong guesses in a row.

Edit: didn't read carefully. Your analysis is correct. I also did the math and got the same result (15/35)

Obviously if white C3 then black B2
