Independent
Events that don't affect occurrence of another event . If P(A∩B)=P(A).P(B), then the two events A and B are independent.

THEOREMS
THEOREM OF TOTAL PROBABILITY : P(E) = P(B1) / P(E/B1) + P(B2) / P(E/B2) +...............+ P(Bn) / P(E/Bn)
BAYE'S THEOREM : Formula : P(B1/E) = [P(B1) / P(E/B1)] / [ P(B1) / P(E/B1) + P(B2) / P(E/B2) +...............+ P(Bn) / P(E/Bn) ]

Types of probability
Conditional probability:P(A/B) denotes probability of occurrence of A given that B has already occurred
Formula:
P(A/B)=P(A ∩ B) / P(B) , but P(B) ≠ 0
