Question

What is the number of all possible matrices of order $2\times 3$ with each entry $0,1$?

Answer 1

The order of the matrix $=2\times 3$

The number of elements $=2\times 3=6$

Each place can have either $0$ or $1$.

Each place can be filled in $2$ ways.

Thus, the number of possible matrices

$=2^6=64$

Hence, this is the answer.
