Determining the Missing Probability in a pmf Graph
A discrete random variable X is represented by a probability mass function (pmf) graph that displays four points corresponding to x = 0, 1, 2, and 3. The given probabilities from the graph are: p(0) = 0.25, p(1) = 0.35, and p(2) = 0.20. Determine the missing probability p(3) such that the total probability is […]
