Marinada '22

[lang=hr] Sitka baca koplje s povezom preko očiju. Meta je sastavljena od tri koncentrične kružnice: radijus crvenog kruga je $1$, zelenog $3$ a plavog $5$ metara. Ako je Sitka bacio koplje nasumično te pogodio metu, koja je vjerojatnost da je pogodio zeleni dio mete? \includegraphics{meta.jpg} [/lang] [lang=en] Sitka is throwing a javelin with a blindfold over his eyes. The target is composed of three concentric circles, where the radius of the red circle is $1$, the radius of the green circle is $3$ and the radius of the blue circle is $5$ meters. If Sitka threw the javelin randomly and hit the target, what is the probability that he hit the green section? \includegraphics{meta.jpg} [/lang]
