Koliko iznosi vjerojatnost (u postotku) da odabirom nasumičnih realnih brojeva x i y koji su veći od -6 ali manji od 7 izaberemo takve brojeve da je x+y \geq 0?
What is the probability (in percentage) that by choosing random real numbers x and y that are greater than -6 but less than 7, we choose such numbers that x+y \geq 0?
