Kocakice | Dicice #4

Igraća kocakica s 6 strana (označenih brojevima od 1 do 6) baca se ponovo, ako padne paran broj. Ako znamo da je u nekom trenutku pala jedinica, kolika je vjerojatnost da je u nekom trenutku prije pada jedinice pala dvojka?
The player's dice with 6 sides (marked with numbers from 1 to 6) are rolled again, if an even number is rolled. If we know that a one fell at some point, what is the probability that a two fell at some point before the one fell?
