The possible values of n are:
1, 5, 7, 11, 13, 17, 19, 23, 25, 29, 31, 35, 37, 41, 43, 47
And the elements in the set are:
\(\frac{1}{24}, \frac{5}{24}, \frac{7}{24}, \frac{11}{24}, \frac{13}{24}, \frac{17}{24}, \frac{19}{24}, \frac{23}{24}, \frac{25}{24}, \frac{29}{24}, \frac{31}{24}, \frac{35}{24}, \frac{37}{24}, \frac{41}{24}, \frac{43}{24}, \frac{47}{24}\)
So the sum of the elements in the set = \(\frac{384}{24}\) = 16
