Okay, here are the steps to solve this problem:
* There are 15 sections of English 102 to choose from
* There are 9 sections of Spanish 102 to choose from
* There are 12 sections of History 102 to choose from
* There are 13 sections of College Algebra to choose from
So for English 102 Felicia has 15 options, for Spanish 102 she has 9 options, for History 102 she has 12 options, and for College Algebra she has 13 options.
By the Fundamental Principle of Counting, the total number of possible schedules is:
15 * 9 * 12 * 13 = 16,920
Therefore, the total number of possible schedules for Felicia is 16,920
