The number of all possible matrices of order `3 xx3`with each entry 0 or 1 is:
(a) 27 (b) 18 (c) 81 (d) 512

Explanation

To find the number of all possible matrices of order \(3 \times 3\) with each entry being either 0 or 1, we can follow these steps:

### Step 1: Determine the total number of entries in the matrix
A \(3 \times 3\) matrix has a total of \(3 \times 3 = 9\) entries.

**Hint:** Count the number of rows and columns in the matrix to find the total number of entries.

### Step 2: Determine the choices for each entry
