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.

This app has made me feel so much more confident in my exam prep, not only through boosting my own self confidence through the features that allow you to connect with others and feel less alone, but also through the way the app itself is centred around making you feel better. It is easy to navigate, fun to use, and helpful to anyone struggling in absolutely any way.

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!

very reliable app to help and grow your ideas of Maths, English and other related topics in your works. please use this app if your struggling in areas, this app is key for that. wish I'd of done a review before. and it's also free so don't worry about that.

I know a lot of apps use fake accounts to boost their reviews but this app deserves it all. Originally I was getting 4 in my English exams and this time I got a grade 7. I didn’t even know about this app three days until the exam and it has helped A LOT. Please actually trust me and use it as I’m sure you too will see developments.
