6. An urn contains 15 red balls and 8 blue balls. In each draw, one ball is extracted at random. It is then returned to the urn, along with 6 extra balls of the same color. (the total number of balls in the urn increases after each draw). Consider the event Ck={a blue ball is extracted at the k-th draw}. Determine the probability P(C4). (at the first three draws the extracted balls are not blue).
