If P(A) = 1/6, P(B) = 1/7, P(ANB) = 1/9
then P(A/B) =​

Answer 1

Answer:

Independence. Two events A and B are called independent if P(A|B)=P(A), i.e., if conditioning on one does not effect the probability of the other. Since P(A|B)=P(AB)/P(B) by definition, P(A)=P(AB)/P(B) if A and B are independent, hence P(A)P(B)=P(AB); this is sometimes given as the definition of independence.
