  2. V osudí je 7 červených koulí a 10 modrých. Namátkou vybereme 4 koule. Jaká je pravděpodobnost, že a)vybrané koule budou stejné barvy, b)mezi nimi budou aspoň 3 červené?

  3. k= 4, n=7+10______________ 1)ANO 2)NE Ck(n) m(A)= n= P=

  4. k= 4, n=7+10______________ 1)ANO 2)NE Ck(n) m(A) = n= P=

  5. Pravděpodobnost, že vybereme koule stejné barvy, je asi 10,3%, že mezi nimi budou 3 červené, je asi 16,2%.
