Problem
An urn contains 4 red balls and 6 blue balls. Two balls are drawn successively without replacement.
(a) State, with reason, whether the event “the second ball drawn is red” is independent of the event “the first ball drawn is blue.”
(b) Calculate P(second ball is red∣first ball is blue). Express your answer as a simplified fraction.
(c) Justify how the value obtained in part (b) supports your answer in part (a).
