(b) 3/8
Then given elements are 0 and So each term of a matrix can be filled (Using or 1) is 2 ways.
The No. of elements is a 2 × 2 matrix = 2 × 2 = 4. So the possible ways of filling the elements of a 2 × 2 matrix is 24 = 16 (i.e.,) n(S) = 16
Let A be the event of getting a 2 × 2 matrix for which the determinant value is non zero.
