Final answer:
The random variable X represents the number of red marbles drawn from a jar. It can take on the values 0 and 1, with the distribution p(x) = 2/3 for 0 and 1/3 for 1.
Step-by-step explanation:
The random variable X represents the number of red marbles drawn from a jar containing three marbles, one blue, one red, and one white. The values that X can take on are 0 and 1, with 0 representing no red marbles drawn and 1 representing one red marble drawn. The distribution of X is given by p(x), where p(0) = 2/3 and p(1) = 1/3.
