Marinada '22

[lang=hr] U jednom malom plesnoj grupi postoje samo 3 dječaka i 5 djevočica. Grupa će otplesati 2 plesa tako da svaki dječak pleše s jednom djevojčicom i nakon oba plesa sve djevojčice su plesale barem jedanput. Jedna od tih djevojčica je Alice, a jedan od tih dječaka je Bob. Kolika je vjerojatnost da oni u oba plesa plešu zajedno? [/lang] [lang=en] In one small dance group there are only 3 boys and 5 girls. The group will perform 2 dances such that each boy dances with one girl and after both dances every girl has danced at least once. One of these girls is Alice, and one of these boys is Bob. What is the probability of them performing both dances together? [/lang]
