What is the roster form of the set of vowels occurring in the word “mathematics”?
Answer and explanation
Correct answer: G={a,e,i}
The letters of “mathematics” are m, a, t, h, e, m, a, t, i, c, and s. The vowels that occur are a, e, and i; the vowel o does not occur. A set records distinct elements only once, so the repeated letter a must not be written twice. Thus the correct roster form is G={a,e,i}, given in option A.
