Probability of Complementary Events

Very Hard

(Originais Teachy 2023) - Question Very Hard of Mathematics

An urn contains 3 red balls and 2 blue balls. A player draws a ball from the urn, observes its color, and puts it back in the urn. Then, they draw another ball and repeat the observation and replacement procedure. After that, the player draws a third ball and does not put it back in the urn. Considering that the color of each drawn ball is independent of the colors of the other balls and that the balls, after being replaced, are distributed equally in the urn, calculate the probability that the first ball drawn is red, the second ball is blue, and the third ball is also blue.
