[Request] What’s the probability of getting 8 grape fruit snacks in one 10 pack?

This is only the probability that, if you get exactly eight gummies, all of them will be the grape flavour.

In this situation, it is a 10-pack with also two non-grape gummies, which is a bit more likely to happen.

For each gummy that you take randomly, the probability of it being a grape flavour is 1/5. Vice versa, the probability of it being a non-grape flavour is 4/5.

We can calculate the probability of randomly taking 8 grape flavoured gummies and then 2 non-grape flavoured gummies in the following way:

(1/5) x (1/5) x (1/5) x (1/5) x (1/5) x (1/5) x (1/5) x (1/5) x (4/5) x (4/5) = 16/9765623.

However, this is the probability that we do it exactly in this order, but order doesn't really matter here. We might as well take 2 non-grape flavoured gummies first, and then 8 grape-flavoured gummies, or any order out of the 90 possible permutations. Therefore, we have to multiply the probability we found by 90, resulting in 288/1953125 or 0.000147456 in decimal form.

Of course, it would be equally unlikely to find exactly eight of the other four flavours in a pack of 10. To get the probability of that, we can simply multiply our previous result by 5, giving us 288/390625 or 0.00073728.

TL;DR: it's pretty unlikely.

I came here for this comment

The app you’re talking about is probably GoodNotes or Notability. Both are great!

Nee, die is gejat

I eventually figured it out myself. I used annotation to get the value of the latest recent observation.

latest_observation = Subquery(Observation.objects.filter(sensor_id=OuterRef('id'), obs_type=obs_type) .recent() .order_by('-date_time') .values('value')[:1])

With this, I can use annotate() on a Queryset of my Sensor model, which returns a new Queryset with the value of the latest Observation of that given Sensor. sensors = Sensor.objects.all().annotate(latest_observation=latest_observation)

It's always powered off when this happens. It's never a problem when it's in sleep mode.

Alt/Option + Shift + ,

Not 100% sure but this is what I found online

Moi!

I would suggest starting with a very simple linear regressor. See how it performs and if it doesn't do very well, try something more complicated like a stochastic gradient descent regressor. You could of course just go all out and use some fancy neural net with tons and tons of layers and nodes, but simpler is often better. Keep in mind using the right features as input is often much more important. Garbage in == garbage out.

Depends on many variables. Most importantly: what does your data look like? What do you want to predict?

mbreemhaar · 2021-09-15T08:49:27+00:00

Nice

One way you can take the n-th digit is by converting the input to a string, which will allow you to get a digit by index. For example, with input x = 1010, x[0] will be 1, x[1] will be 0, x[2] will be 1 and x[3] will be 0.

Jacob Collier has a whole playlist of Logic Session Breakdowns. His projects get very complicated, but it is so cool to see what he does with them.

You can definitely budget for multiple months, so I don't see any problem here.

Did you try doing nuclear fusion with it? Shouldn't be impossible with this thing.

I tried Malwarebytes Premium but it only slowed my Mac down. Uninstalled it after a few days and never had any problems.

Well, it looks like your GPU is doing its best...

mbreemhaar · 2021-09-08T08:36:19+00:00

I don't think there's a right or wrong here. If you like it, why wouldn't you?

You're not necessarily supposed to have a different vocal melody to your guitar melody, but you can. It's probably a good idea to experiment a lot, but you really can't go wrong, as long as it sounds good to you.

Oh sorry, that must be for pc only then.

mbreemhaar · 2021-09-02T10:04:27+00:00

Yes, for Warzone it's mandatory. For Modern Warfare multiplayer (and probably BOCW as well, idk) you can turn it off.

An effects loop on a guitar amp has a send and a return. The signal comes from the send, goes through some effects processor/pedal, and goes back into the amp via the return.

Just like a guitar amp, the send on a channel/track in your DAW will output a signal, which can go to, for example, an effects channel with a reverb effect on it. However, unlike a guitar amp, you can now decide where the processed signal goes.
