Two events, A and B, are associated with the following probabilities:

P(A)=2/3

P(A∩B)=2/9

If the events are independent, what is the probability of B?

P(B)= __[blank]__

Enter your answer as the fraction that correctly fills in the blank, using the / symbol, like this: 42/53

Zarkon · Answer

If A and B are independent then $P(A\cap B)=P(A)P(B)$

then $$\frac{2}{9}=\frac{2}{3}P(B)$$

solve for $P(B)$
