Question
Matrices are formed using four given distinct real numbers, taking all at a time, of all possible orders. Number of such distinct possible matrices is -
Options
A.12
B.24
C.48
D.72
Solution
Possible orders : 1 × 4; 4 × 1; 2 × 2
Number of possible matrices
= 4! + 4! + 4! = 72
Number of possible matrices
= 4! + 4! + 4! = 72
