A bag contains one red marble, two blue marbles and three green marbles. A marble is selected at random. Define a random variable X such that X=1 if a red marble is selected, X=2 if a blue marble is selected and X=3 if a green marble is selected. Find the following probabilities. Hint: The blue marbles are different; you can label one blue-1 and the other blue-2. Similarly, each of the green marbles is different. 4a) Find P(X=1) 4b) Find...
