Multiple choice: Select the best answer.
In government data, a household consists of all occupants of a dwelling unit. Choose an American household at random and count the number of people it contains. Here is the assignment of probabilities for the outcome:
\(\begin{array}{lccccccc} \hline \text { Number of persons: } & 1 & 2 & 3 & 4 & 5 & 6 & 7+ \\ \text { Probability: } & 0.25 & 0.32 & \text { ??? } & ? ? ? & 0.07 & 0.03 & 0.01 \\ \hline \end{array}\)
The probability of finding 3 people in a household is the same as the probability of finding 4 people. These probabilities are marked ??? in the table of the distribution. The probability that a household contains 3 people must be
(a) \(0.68\).
(b) \(0.32\).
(c) \(0.16\).
(d) \(0.08\).
(e) between \(0\) and \(1\), and we can say no more.
