Answer: 96 ways In this case, the freshman must take one class each from Science(6 courses), Humanities(4 courses) and Mathematics( 4 courses). Then to know how many ways she can arrange you just need to multiply the each course count (it would different if she has to take more than one class). The calculation would be: 6 x 4 x 4= 96 ways.
