Osnove verjetnosti: Izračun verjetnosti dogodkov
1 / 5
Kaj je verjetnost in zakaj je pomembna?
Verjetnost je kot napovedovanje prihodnosti s števili. Ko slišiš "70% možnost dežja", to je verjetnost v akciji! V matematiki se naučiš to možnost natančno izračunati.
Poskus je dejanje, pri katerem ne veš vnaprej, kaj se bo zgodilo - kot metanje kocke. Izid je en možen rezultat (npr. pade število 3), dogodek pa je tisto, kar opazuješ (npr. pade sodo število).
Poznati moraš tri vrste dogodkov: nemogoč dogodek , slučajen dogodek (verjetnost med 0 in 1) in gotov dogodek .
Zapomni si: Pri kocki je nemogoče, da pade 7, slučajno, da pade 3, gotovo pa, da pade število manjše od 7!
Glavna formula za izračun verjetnosti
Tu je formula, ki jo moraš obvladati: P(A) = število ugodnih izidov / število vseh možnih izidov. Tako preprosto!
Koraki so vedno enaki: ugotovi poskus, preštej vse možne izide, določi ugodne izide za svoj dogodek, nato vstavi v formulo. Če lahko, ulomek vedno okrajšaj.
Verjetnost je vedno število med 0 in 1. Lahko jo zapišeš kot ulomek (1/2), decimalno število (0,5) ali odstotek (50%).
Praktičen namig: Če ti pri kocki pade "sodo število", so ugodni izidi 2, 4, 6 - torej 3 od 6 možnih!
Rešeni primeri - met kocke
Pri standardni kocki imaš vedno 6 možnih izidov: {1, 2, 3, 4, 5, 6}.
Če te zanima verjetnost, da pade število 5, imaš 1 ugoden izid od 6 možnih. Torej P(A) = 1/6. Če pa te zanima, da pade število večje od 2, so ugodni izidi {3, 4, 5, 6} - to je 4 od 6.
Izračun: P(B) = 4/6 = 2/3. Pomembno: ulomek si okrajšal z 2!
Preveri se: Ali znaš ugotoviti, kateri izidi so ugodni za tvoj dogodek? To je ključ do uspeha!
Rešeni primeri - barvne kroglice
V vrečki s kroglicami najprej sešteješ vse kroglice: 5 rdečih + 3 modre + 2 zeleni = 10 kroglic skupaj.
Za modro kroglico: P(C) = 3/10 = 30%. Za rumeno kroglico pa P(D) = 0/10 = 0, ker rumenih sploh ni - nemogoč dogodek!
Glavna formula, ki si jo zapiši: Verjetnost = Število ugodnih možnosti / Število vseh možnosti. To je tvoje orodje za vse naloge.
Pozor na napako: Vedno najprej izračunaj skupno število vseh možnosti - to je imenovalec!
Hiter povzetek za test
Ključne stvari za obvladovanje: P = 0 pomeni nemogoč dogodek, P = 1 pomeni gotov dogodek. Vmes so vsi slučajni dogodki.
Pri metu kocke imaš 6 možnosti, pri metu kovanca 2 možnosti. Pri kroglicah vedno sešteješ vse kroglice v vrečki.
Zadnji korak: ulomek vedno okrajšaj, če se da. Če te sprašuje za odstotke, pretvori .
Pred testom preveri: Ali znaš formulo, ali ločiš izid od dogodka in ali znaš okrajšati ulomek?

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

I think it’s very much worth it and you’ll end up using it a lot once you get the hang of it and even after looking at others notes you can still ask your Artificial intelligence buddy the question and ask to simplify it if you still don’t get it!!! In the end I think it’s worth it 😊👍 ⚠️Also DID I MENTION ITS FREEE YOU DON’T HAVE TO PAY FOR ANYTHING AND STILL GET YOUR GRADES IN PERFECTLY❗️❗️⚠️

Knowunity is the BEST app I’ve used in a minute. This is not an ai review or anything this is genuinely coming from a 7th grade student (I know 2011 im young) but dude this app is a 10/10 i have maintained a 3.8 gpa and have plenty of time for gaming. I love it and my mom is just happy I got good grades

Not only did it help me find the answer but it also showed me alternative ways to solve it. I was horrible in math and science but now I have an a in both subjects. Thanks for the help🤍🤍

The app's just great! All I have to do is enter the topic in the search bar and I get the response real fast. I don't have to watch 10 YouTube videos to understand something, so I'm saving my time. Highly recommended!

In school I was really bad at maths but thanks to the app, I am doing better now. I am so grateful that you made the app.

I found this app a couple years ago and it has only gotten better since then. I really love it because it can help with written questions and photo questions. Also, it can find study guides that other people have made as well as flashcard sets and practice tests. The free version is also amazing for students who might not be able to afford it. Would 100% recommend

Best app if you're in Highschool or Junior high. I have been using this app for 2 school years and it's the best, it's good if you don't have anyone to help you with school work.😋🩷🎀

This app is phenomenal down to the correct info and the various topics you can study! I greatly recommend it for people who struggle with procrastination and those who need homework help. It has been perfectly accurate for world 1 history as far as I’ve seen! Geometry too!
