1. An urn always contains 2 balls, and ball colors are either red or blue. At each stage, a ball is randomly chosen (i.e., each ball chosen with probability 0.5) and replaced by a new ball. The new ball is with probability 0.8 of the same color as the ball it replaces, and with probability 0.2 the opposite color as the ball it replaces. If initially both balls are red, find the probability that the fifth ball selected is red.
