Question

Which type of number system contains only the combinations of 0's and 1's?

• A. Binary
• B. Decimal
• C. Prime
• D. Even

Answer 1

The correct option is A

Binary

The binary numeral system represents numeric values using two different symbols: typically 0 (zero) and 1 (one).

Decimal number system in mathematics requires 10 different numerals, the digits 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.

Prime and even numbers are not number systems. They only represent a certain section of numbers in mathematics.

So the correct answer would be 'binary'. It is to be noted here that the decimal number system also contains the number 0 and 1. However, it contains other numbers too, such as 2, 3, 4, etc. But the binary system only contains two digits, that is, 0 and 1.
