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 your outcome: Number of persons 1 2 3 4 5 6 7
Probabilities 0.25 0.32 ??? ??? 0.07 0.03 0.01
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.
