Why do Minerva and Trujillo roll the dice? does Trujillo propose to play?8

Minerva notices a set of dice on Trujillo's desk, and she realizes that they are loaded. She makes a bet with him: they will roll the dice, and if she wins, she can go to law school, but if he wins, he gets to sleep with her. Minerva knows to use the heavier set of dice, and of course she wins, to Trujillo's annoyance.
