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^2 + y^2 \leq 36?
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^2 + y^2 \leq 36?
