meaning there's a 1-in-75 chance

.ما يعني أن هناك فرصة 1 من 75 أن تربطوا بأي شخص
vu qu’il y a 5 classes
de 15 filles et 15 garçons.
perciò ho una possibilità su 75
 di finire in coppia con lei...
então há uma chance de 1 em 75
de ser par com qualquer pessoa.
значит, шанс стать парой с ней —
один из семидесяти пяти.
