Answer
$\frac{23}{174}$
Work Step by Step
P(E) = $\frac{no.\ of\ outcomes\ in\ favor}{Total\ no.\ of\ outcomes}$
We use the data in the table from the textbook to find the probability of a given education level. A total of 174 million people were included in the US Census Bureau study.
E: Was a man with four years of college or more.
Favorable outcomes= {23}
P(E) = $\frac{23}{174}$
