He knows that if Cathy is going to go to class he will hear her fixing herself breakfast. Cathy knows that Phil may or may not go to class depending on what she does. The timing of their decisions and their respective payoffs are as represented by the diagram below, where choosing the upper path means go to class and choosing the lower path means don€™t go to class.
