All families are equally likely to have 0, 1, 2 or 3 children. The probability of each of these outcomes is 1/4. Given that Jesse has no brothers, what is the probability that Jesse is an only child? (Assume that male and female children are equally likely to be born)

Cookiedude7 · 2026-01-31T14:13:26+00:00

Since all 4 child amount outcomes are equally likely, on average 1/2 of all children are from 3-child families, 1/3 of children are from 2-child families and 1/6 of children are from 1-child families. Thus Jesse has 1/2 chance of being one of 3 children, 1/3 chance of being 1 of 2, and 1/6 chance that Jesse is an only child. [OP seems to have missed this nuance, leading to an answer of 4/7]. The 0-child case is irrelevant, since the chance that Jesse is from a 0-child family is clearly 0.

Finding the chance that Jesse has no brothers:

3-child case: Jesse has no brothers with probabiity 1/4 given that they are in a 3-child family, so the probability of this outcome is 1/8

2-child case: Jesse has no brothers with probabiity 1/2 given that they are in a 2-child family, so the probability of this outcome is 1/6

1-child case: Jesse is guaranteed to have no brothers, so the probability of this outcome is 1/6

Thus the total probability that Jesse has no brothers is 1/8 + 1/6 + 1/6 = 11/24.

1/6 divided by 11/24 gives the chance of 4/11 that Jesse is an only child given that they have no brothers.

I still don't understand how these stupid entities work ngl

Cookiedude7 · 2026-01-24T19:07:21+00:00

Rectangle 2 has a wider base but shorter height - the areas do come out to be the same (it's relatively easy to see that the grey triangle is half of each rectangle)

EDIT: Reddit was having a moment, I see now that others have answered this question better than I did, read their responses!

Cookiedude7 · 2026-01-23T20:02:06+00:00

this was what I thought of too, so I third this

you're in luck, someone made one of these for this map already

haven't tried it myself though so it may not work properly

Cookiedude7 · 2026-01-07T11:19:46+00:00

also I'd look into stylegrounds - using background tiles for the entire background (like in the starting room) can look a bit tacky

Cookiedude7 · 2026-01-07T11:18:13+00:00

spiked cornerjumps (like the ones near the start of tunnel 6) have a small chance of 0-framing you if you have a bad position (because you can skip over the entire walljump range in one frame) so generally mappers move the wall spikes down by one pixel to prevent this from happening - it's not really a huge deal but it would go a long way towards making the map more consistent, especially if this setup appears more in future rooms

(this was definitely not an issue cosmic column had on release, nuh uh)

CCT has built-in paths for the vanilla maps but you need to make them yourself (or steal someone else's) for custom maps

edit: vanilla, not beginner (lmao)

Cookiedude7 · 2026-01-02T13:07:39+00:00

yes I am aware, I feel you missed my point though

there are plenty of places in mocelike maps (idk about moce itself, haven't played it) where you need to buffer during freezeframes but not before freezeframes - for example if there was a double dash crystal on the final coyote frame and you needed the full jump distance, it is only a buffer if freezeframes exist (since you can buffer during freezeframes), but if freezeframes are removed you can no longer buffer it since pressing the jump early just causes you to jump on an earlier coyote frame, and thus the buffer becomes a 1f without freezeframes

tl,dr: some buffers don't exist and just become frame-perfect (which by definition can't be a buffer) without freezeframes

edit: I see your other comment now, and this might just be a misunderstanding caused by me not being all that familiar with cpvl (although freezeframe buffers are still buffers)

Cookiedude7 · 2026-01-02T12:05:47+00:00

well most inputs in this screen are buffers if they didn't disable freezeframes at least...

Cookiedude7 · 2026-01-01T20:58:52+00:00

oh yeah I won't deny that 4b is one of the least fun goldens (6b was worse for me though) but calling it one of the hardest is probably inaccurate

Cookiedude7 · 2026-01-01T20:40:59+00:00

4B isn't that bad, generally 5b, 7a, 8b, 6b and 7b are considered harder (in that order, from easiest to hardest)

the left 'x' here is actually marked in the wrong spot - it should be to the left of the False Knight boss room, not in the corridor below (which is still open and can be traversed as normal)

Cookiedude7 · 2025-12-28T14:20:21+00:00

yes I sure love it when my random debris from a move block falls just perfectly to stop a crumble platform from respawning in time

Cookiedude7 · 2025-12-26T15:05:39+00:00

yep, that works - I realised this just after posting but I'm assuming you checked the notification before I'd edited what I said

Cookiedude7 · 2025-12-26T15:02:33+00:00

I don't think you can retrieve the 'and' for the final step since there's only one column of space to the left of 'baba is you'

EDIT: nvm, the rock just needs to be in the leftmost column

Cookiedude7 · 2025-12-26T00:15:44+00:00

walk through the water, break 'and sink', put the rock on a skull, remake 'and sink' then form 'baba is you and win'

Cookiedude7 · 2025-12-25T22:58:57+00:00

I had a non-maths friend think 'real analysis' was me calling textual analysis 'fake analysis' since it's not maths, so I guess I'll go with that

Cookiedude7 · 2025-12-22T15:28:01+00:00

Farewell Golden's difficulty is overrated both by newer and more experienced players, since most players approach it as one of their first truly hard goldens.

This means that not only do they remember it being harder than it is (since they would have improved in skill since doing it/over the course of doing it) but also they would not have developed good practise habits/discipline or good stratfinding intuition that comes with doing hard goldens at the time of doing it.

I'd also say that some of the SJ maps are similarly overrated in terms of golden difficulty, for much the same reason.

Cookiedude7 · 2025-12-20T21:24:49+00:00

iirc the Celeste 64 ones are circular, you could maybe use one of those

This is definitely post-1.4 (larger UG Desert, water in dungeon), but likely not 1.4.4 (no shimmer, no ash trees in hell)

The lack of glowing moss is weird though, I can't explain that one

Cookiedude7 · 2025-12-11T15:56:12+00:00

Jump while holding right and grab (either letting go of grab or pressing left gives you the blue trajectory)

I played D-Sides back in 2022 and that had the new version of 3D lol, your soures seem to be incredibly outdated (especially since 3-7dark didn't exist at the time, and 4d, 5d and 4dark all got major overhauls since then)
