a)pt Diana probabilitatea=nr cazurilor favorabile/nr cazurilor posibile= 5/15=1/3
pt Adrian p=9/24= 3/8
1/3 de comparat (pui casuta) 3/8 aducem la acelasi numitor
8/24 ( < ) 9/24
Adrian are o sansa mai mare sa extraga o bila neagra
b)pt Diana p= 10/15= 2/3
pt Adrian p= 15/24= 5/8
2/3 ( ) 5/8 aducem la acelasi numitor
16/24 ( > ) 15/24
Diana are o sansa mai mare sa extraga o bila alba
c) 2/3 = 5/8 aducem la acelasi numitor
32/48 = 30/48, in urna lui Adrian mai trebuiau sa fie 2 bile
