Explain how would you use combination of random variables to solve the following problem and show its solution. In a game a player either wins $10 with a probability of 1/8 or loses $1 with a probability of 7/8. What are the expectation and standard deviation of the total net winnings of a player after 50 turns at the game?
Extra Question: Post an example not discussed neither in class, nor in quizzes on calculating the variance of the difference of two random variables.

First, you will need to create the Creature class. Creatures have 2 member variables: a name, and the number of gold coins that they are carrying. Write a constructor, getter functions for each member, and 2 other functions: - void addGoldCoins(int) adds gold coins to the Creature. - void identify() prints the Creature information. The following should run in main: Creature d{"dragon", 50}; d.addGoldCoins(10); d.identify(); // This prints: The dragon is carrying 60 gold coins. Second, you are going to...

2. For each of the following random variables: • Decide whether it would be appropriate to model it as a Bernoulli, binomial, geometric, or Poisson distribution, or none of the above. Explain briefly why these choices are appropriate, including any independence assumptions. If appropriate, give the parameter value(s). • Determine the expected value, variance, and standard deviation of the random variable. If it follows one of the special distributions, you can use the known formulas discussed in class. (If multiple...
