Question

G={xlx is a 3-digit number less than 100}​

Answer 1

Explanation:

The set G represents all the three-digit numbers that are less than 100.

In this case, since the numbers must be three digits, they must have a hundreds place, a tens place, and a ones place. However, if a number is less than 100, it cannot have a hundreds place.

Therefore, the set G is an empty set or a null set since there are no three-digit numbers that are less than 100.

In set notation, we can represent this as:

G = {} or G = Ø

So, in summary, the set G is empty as there are no three-digit numbers less than 100.
