Answer
0.14
Work Step by Step
P(E) = $\frac{no.\ of\ outcomes\ in\ favor}{Total\ no.\ of\ outcomes}$
The table in the book shows the distribution of people who live alone. We use the data to find the probability of a given outcome. We know that there are 29.3 million total outcomes.
E: in the 35–44 age range.
Favorable outcomes= {4.2 million}
P(E) = $\frac{4.2}{29.3}$ =0.14
