spinner has 3 equal sections that are labeled 1,2, nd 3. If the spinner spins twice, find the sum of the vo numbers it lands on. Let X be the random ariable that represents the sum of the two numbers. 3 a. List all sample spaces and identify how many they are. b. Let X be the random variable that represents the sum of two numbers. What are the possible values of X? c. Illustrate a probability distribution for a random variable X. D. Show the sum of all the probabili ties of all values of the random vari able (X) is equal to 1.E P(X) =1
