Question

The number of all possible matrices of order 3×3 with each entry 0 or1 is

Answer 1

In a 3×3 matrix, we have total 9 places to fill.

Each place can be filled by either 0 or 1. So 2 ways of filling each place

So total possible ways = 2×2×2×... 9 times = 2^9

So number of possible matrices = 2^9 = 512
