Which of the following are valid probability distributions for a discrete random variable? Check all that apply. A.(0.01) 11, (0.01) 12, (0.01) 13, ... B.0.19, 0.19, 0.225, 0.231, 0.164 C.0.14, -0.04, 0.28, 0.10, 0.13, 0.07, 0.13, 0.29, 0.34, -0.27, -0.22, 0.05 D.0.34, 0.19, 0.20, 0.07, 0.16, 0.04 E.0.17, 0.11, 0.03, 0.07, 0.23, 0.04, 0.16, 0.01, 0.18
not an expert in this topic, but i feel it should be A? others seem to make no sense to me.
Im pretty sure it is more than just A. it can be more than one answer to this problem,.. IDK it confuses me,
i think your job may be to add the numbers and see if the total is 1
All the probabilities must be between 0 and 1 inclusive The sum of the probabilities of the outcomes must be 1. Read more at the link: http://people.richland.edu/james/lecture/m170/ch06-prb.html
