A box contains $\displaystyle 5$ white and $\displaystyle 7$ black balls. Two successive drawn of $\displaystyle 3$ balls are made (i) with replacement (ii) without replacement. The probability that the first draw would produce white balls and the second draw would produce black balls are respectively.

According to bayee's theorem, $\displaystyle P(E_i / A) = \frac{P(E_i)P(A / E_i)}{\sum_{j=1}^{n} P(E_j)P(A / E_j)}$ here
