The table below shows the probabilities of the number of occupants in a housing unit under each of the two conditions. Create a tree diagram using this information and use it to answer the following questions: We rst create the tree diagram using the information given, and use the multiplication rule to ll in the probabilities at the ends of the branches. 1 (c) this is a conditional probability (or bayes? rule). If a housing unit has only 1 occupant, the probability that it is rented is 0. 474. 11. 83 owner-occupied household size (graded for accurateness) the table below gives the probability function for the random variable giving the household size for an owner-occupied housing unit in the us. x.
