A lottery company created a new game. In a large container, they place a large number of red, blue and yellow balls. At the bottom of the container there is a button, which, if pushed, will randomly draw three balls from the container. A participant wins $150 if the outcome of the random draw is two yellow balls and one blue ball, $250 if the outcome is two yellow balls and one red ball, or $1000 if the outcome is three yellow balls. Otherwise the participant wins nothing. It costs $5 to play this game once. One participant concludes that each container approximately consist of 35% red balls, 55% blue balls, and 10% yellow balls. If this is true, what is the variance of net earnings after playing one game?

Discrete Mathematics classwork (2024/4/19) Name: Student ID: $ 223002(\omega) $ The graph in below figure is a directed graph $ G $. The direction of the edges $ (2,3),(2,4) $ and $ (5,1) $ is given. Label the direction of the edges $ \{1,4\},\{1,2\},\{1,3\} $ and $ \{3,5\} $ so that the directed graph $ G $ has a Euler trail. Explain the choice of direction of edges $ \{1,4\},\{1,2\},\{1,3\} $ and $ \{3,5\} $. Find one of the Euler trails.
