How many 3x3 matrices with entries 0 1 2

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. WebThe dimensions of a matrix give the number of rows and columns of the matrix in that order. Since matrix A A has 2 2 rows and 3 3 columns, it is called a 2\times 3 2×3 matrix.
