Answer to Question 1

B

Answer to Question 2

Answers will vary. Possible answer: You are more likely to make a profit in one play of game A than in one play of game B. The standard deviation of X is larger than the standard deviation of Y which means that there is a greater chance that X could be so far from the mean.
