/___/
/___/__114__/ total=412
412-114=298
stabilim egalitatea:
298:2=149 porumbei albi
149+114=263 porumbei gri
proba: 149+263=412
/___/__114__/ total=412
412-114=298
stabilim egalitatea:
298:2=149 porumbei albi
149+114=263 porumbei gri
proba: 149+263=412
porumbei gri = |_______|
porumbei albi = |______|
|_| diferente de 114 porumbei
|________|+|______|_| = (412+114) : 2 = 263 (porumbei gri)
si 263 - 114 = 149 (porumbei albi)
porumbei albi = |______|
|_| diferente de 114 porumbei
|________|+|______|_| = (412+114) : 2 = 263 (porumbei gri)
si 263 - 114 = 149 (porumbei albi)
