Question

Express the given sets in roster form:

(xii) $H=\{x:x\in Wandx<10\}$

Answer 1

Step: Expressing set H in roster form

In roster form, the elements of the set are written inside a pair of curly braces and are separated by commas.

Given: $H=x:x\in Wandx<10$

where, $W$ represents whole numbers.

$\therefore$ Whole numbers less than 10 are 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9.

Hence, the roster form of set is

H = { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9}.
