# Abox contains four red balls and eight black balls. two balls are randomly chosen from the box, and are not replaced. let event b be choosing a black ball first and event r be choosing a red ball second. what are the following probabilities? p(b) = p(rib) = pbr) = the probability that the first ball chosen is black and the second ball chosen is red is about percent.   ### Other questions on the subject: Mathematics Mathematics, 08.07.2019 20:30, aliami0306oyaj0n
Abox contains four red balls and eight black balls. two balls are randomly chosen from the box, and are not replaced. let event b be choosing a black ball first and event r be choosing a red ball second. what are the following probabilities? p(b) = p(r | b) = p(b ∩ r) = the probability that the first ball chosen is black and the second ball chosen is red is about percent.
