The incomplete probability distribution table at the right is of the discrete random variable x representing the number of dogs owned by each family in a small town. Answer the following: (b) Find the probability that x is at least 2 , that is find P(x 2). 0 0.331 0.275 2 (Hint: what are the requirments for a probability distribution?) P(X=x) 1 (a) Determine the value that is missing in the table. x 0.213 3 4 Total (c) Find P(x 3). Describe what the resulting value represents within the given context. (d) Find the mean (expected value) and standard deviation of this probability distribution. 0.012 10
