1. Consider the following random experiment: there is a bag with 4 marbles in it, two red and two blue. We draw two marbles from the bag, without replacement. To make the sampling uniform, let's label the two red marbles R₁ and R2 and the two blue marbles B₁ and B2. Then the sample space is {R₁R2, R₁B₁, R₁B2, R2B1, R2B2, B1B2}. Finally, let X be the indicator variable equal to 1 if the two marbles drawn have the same color, and 0 if they have different colors. (a) Write down X as a function from the sample space to the real numbers. (b) What is Rx, the range of X? (c) Write down the probability mass function Px of X: this is a function from the range of X to the interval [0, 1]. (d) Identify the distribution of X by name, and give the parameter(s) of that distribution. (The functions in parts (a) and (c) of this problem both have only finitely many possible inputs. I don't care what notation you use in your answer, as long as you give me the value of the function for every possible…
