Determine whether the following is a probability distribution. If not, identify the requirement that is not satisfied. Remember that you have to check the two requirements for discrete probability distributions. P(X) 0.109 1 0.208 0.246 3 0.159 4. 0.096 0.228 Not a probability distribution. The sum of the P(x)'s is not 1, since 1.046 # 1.000. Definitely a probability distribution. 2.
