Answer
0.13
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.
E: In the 25–34 age range
Favorable outcomes= {3.8}
P(E) = $\frac{3.8}{29.3}$ =0.13
