WebA 3x3 matrix has a total of 3 x 3 = 9 elements. Now the permitted values for a matrix cell is only either 0 or 1. So, there are two possibilities of a value for any cell. As their are 9 cells in total so the total number of possible matrices would be 2 x 2 x 2 … 2 (2 multiplied with itself 9 times). So the total number of matrices would be 2^9.
