Question

Write the set in Roaster Form:

(e) $\left\{\text{Vowels used in word 'AMERICA'}\right\}$

Answer 1

Steps: Writing the set in Roaster Form
Vowels in the word $\text{'AMERICA' are A,E,I,A.}$
But a letter should be written only once in a set.​
We use lowercase for elements while writing in set.​
Hence, the required roaster form of set is $\{a,e,i\}$.
