Two extractions are made without re-entry from an urn that has 8 Red and 12 White balls. What is the probability that the second ball is red?
Having the $\Omega = 380$, how would you solve it without adding probabilities? Or how many ways can it be solved? Also, do you find the question clear? Because I read it in an online fun quiz and it seems to me it should be more specified, for example it should mention whether two extractions are a one time event or two extractions with successions. Is that right?
