The number of all possible matrices of order 3×3 with each entry 0 or 1 is

Explanation:

The number of elements in a 3 × 3 matrix is 9.

The number of entries is 2.

Each of the nine elements can be given by either 0 or 1.

Hence, the number of all possible matrices will be,

2⁹=512

Final answer:

The number of all possible matrices of order 3×3 with each entry 0 or 1 is 512.
