1. In chess there are three outcomes (W-Win, L-Loss, D-Draw). Mike is a great chess player. The probability that he W-wins in chess is six times the probability that he loses. The probability that he Draws is 3 times the probability that he loses. Mike is scheduled to play two games today. What is the probability that he loses both? Assume outcomes of consecutive games are independent.
