Exercise 1. Independence

Imagine you draw two balls from a box containing colored balls. You either replace the first ball before you draw the second or you leave the first ball out of the box when you draw the second ball.

Under which situation are the two draws independent of one another?

Remember that two events \(A\) and \(B\) are independent if \(\mbox{Pr}(A \mbox{ and } B) = \mbox{Pr}(A) P(B)\).
