Answer

The probability that a randomly picked American has not done 4 years of high school is $\frac{1}{6}$.

Work Step by Step

We know that the probability that a randomly picked American has not done 4 years of high school can be computed by putting the values from the table in the formula as given below: $\begin{align} & P\left( \text{has not completed 4 years of high school} \right)=\frac{29}{174} \\ & =\frac{1}{6} \end{align}$ Thus, the probability that a randomly picked American has not done 4 years of high school is $\frac{1}{6}$.
