determinant is zero. A square matrix A has inverse if and only if A is non-singular. Unique 
solution of equation AX = B is given by X = A–1 B, where A ≠ 0. A system of equation is 
consistent or inconsistent according to as its solution exists or not. For a square matrix 
A in matrix equation AX = B 
(i) | A| ≠ 0, there exists unique solution 
(ii) | A| = 0 and (adj A) B ≠ 0, ta hen there exists no solution 
(iii) | A| = 0 and (adj A) B = 0, then system may or may not be consistent.

0 ≤ P (E|F) ≤ 1, P (E′|F) = 1 – P (E|F) 
P ((E ∪ F)|G) = P (E|G) + P (F|G) – P ((E ∩ F)|G) 
P (E ∩ F) = P (E) P (F|E), P (E) ≠ 0 
P (E ∩ F) = P (F) P (E|F), P (F) ≠ 0 
If E and F are independent, then 
P (E ∩ F) = P (E) P (F) 
P (E|F) = P (E), P (F) ≠ 0 
P (F|E) = P (F), P(E) ≠ 0 
The theorem of total probability 
Bayes’ theorem 
A random variable is a real-valued function whose domain is the sample space of a 
random experiment. 
Var (X) = E (X2) – [E(X)]2 
Trials of a random experiment are called Bernoulli trials if they satisfy the 
following conditions : 
There should be a finite number of trials. 
The trials should be independent. 
Each trial has exactly two outcomes: success or failure. 
The probability of success remains the same in each trial.
