Set D is the set of the distinct letters in the word mathematics. Write the set using the Roster method.
D = {m, a, t, h, e, m, a, t, i, c, s}
D = {m, a, t, h}
D = {m, a, t, h, e, i, c, s}
D = {m, a, t, h, i, c, s}
Set C is the set of whole numbers less than 9. Write the set using the Roster method.
C = {1, 2, 3, 4, 5, 6, 7, 8, 9}
C = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}
C = {1, 2, 3, 4, 5, 6, 7, 8}
C = {0, 1, 2, 3, 4, 5, 6, 7, 8}
