Answer: There are 30 possible schedules.
Step-by-step explanation:
Given : Number of choices for mathematics courses = 2
Number of choices for science courses = 3
Number courses of social sciences and humanities=5
By using Fundamental counting principle , the number of different possible schedules :
( Number of choices for mathematics courses ) x ( Number of choices for science courses) x (Number courses of social sciences and humanities)
2 x 3 x 5 = 30
Hence, the number of possible schedules = 30
