  • Definition of Determinant
    • For a given matrix, A = [a11]1 × 1 its determinant is defined as det a11 or |a11| = a11
    • For a 2 × 2 matrix, X = \begin{bmatrix} a & b \\ c & d \end{bmatrix},                   the determinant is defined as, |X|= \begin{vmatrix} a & b \\ c & d \end{vmatrix} = ad - bc
    • For a 3 × 3 matrix, A = \begin{bmatrix} a_{1} & a_{2} & a_{3} \\ b_{1} & b_{2} & b_{3} \\ c_{1} & c_{2} & c_{3} \end{bmatrix}                    the determinant is defined as |A| =  (-1)^{1 + 1}a_{1}\begin{vmatrix} b_{2} & b_{3} \\ c_{2} & c_{3} \end{vmatrix} + (-1)^{1 + 2}a_{12}\begin{vmatrix} b_{1} & b_{3}   \\ c_{1} & c_{3} \end{vmatrix} + (-1)^{1 + 3}a_{3}\begin{vmatrix} b_{1} & b_{2} \\ c_{1} & c_{2} \end{vmatrix}

\begin{bmatrix}a_{11} & a_{12} &a_{13}\\a_{21} & a_{22} & a_{23}\\a_{31} & a_{32} & a_{33}\end{bmatrix}

The Minor of a12 will be the determinant:

\begin{vmatrix}a_{21} & a_{23}\\a_{31} & a_{33}\end{vmatrix}

  • Cofactor: Cofactors are related to minors by a small formula, for an element aij, the cofactor of this element is Cij and the minor is Mij then, cofactor can be written as:

Cij = (-1)i+j Mij

  • Scalar Multiple Property of determinants: If each element of a row (or a column) of a determinant is multiplied by a constant k, then its value gets multiplied by k

 \begin{vmatrix} ka & kb \\ c & d \end{vmatrix} = k\begin{vmatrix} a & b \\ c & d \end{vmatrix}

  • Sum Property of determinants: If some or all elements of a row or column can be expressed as the sum of two or more terms, then the determinant can also be expressed as the sum of two or more determinants.

\begin{vmatrix} a_{1} + \lambda_{1} & a_{2} + \lambda_{2} & a_{3} + \lambda_{3} \\ b_{1} & b_{2} & b_{3} \\ c_{1} & c_{2} & c_{3} \end{vmatrix} = \begin{vmatrix} a_{1} & a_{2} & a_{3} \\ b_{1} & b_{2} & b_{3} \\ c_{1} & c_{2} & c_{3} \end{vmatrix} + \begin{vmatrix} \lambda_{1} & \lambda_{2} & \lambda_{3} \\ b_{1} & b_{2} & b_{3} \\ c_{1} & c_{2} & c_{3} \end{vmatrix}

Important formulas studied in CBSE Class 12 Chapter 13- Probability:

  • The conditional probability of an event E holds the value of the occurrence of the event F as:

P(E|F) = E ∩ F / P(F), P(F)≠0

  • Total Probability: Let E1 , E2 , …. , En be the partition of a sample space and A be any event; then,

P(A) = P(E1) P (A|E1) + P (E2) P (A|E2) + … + P (En) . P(A|En)

  • Bayes Theorem: If E1 , E2 , …. , En are events constituting in a sample space S; then,

P(Ei|A) = P(Ei) P(A|Ei) / ∑nj=1 P(Ej) P(A|Ej)
