5 . Written task. Please see the marking rubric on Canvas before attempting this problem. In your own words, clearly explain what it means for two discrete random variables to be independent. Give an example of discrete random variables X, and Y such that X and Y are independent. Clearly explain why it is not possible to define an event related to the variable X and an event related to the variable Y which are mutually exclusive (unless at least one of the events is the trivial event which occurs with zero probability.) Define your variables in everyday language, not mathematical notation
