Question

The following table represents the highest educational attainment of all adultresidents in a certain town. If an adult is chosen randomly from the town, what is theprobability that they have a high school degree or some college, but have no collegedegree? Round your answer to the nearest thousandth.

Answer 1

The following represents the highest educational attainment of all adult

residents in a certain town as shown on the question tab

`\begin{gathered} \text{high school degre = 1414 + 1248 +673 +1042} \\ \text{High school degr}ee\text{= 4477} \end{gathered}`

`\begin{gathered} \text{Some coll}ege\text{ = 571+704+1076+2773} \\ \text{Some college = 5124} \end{gathered}`

`\begin{gathered} \text{Probability of chosen an adult with high school degr}ee\text{ or some college=} \\ =\text{ pr(high school degr}ee)\text{ + pr(some college)} \\ =(4477)/(16612)\text{ +}(5124)/(16612) \\ =(4477+5124)/(16612) \\ =(9601)/(16612) \\ =\text{ 0.57796} \\ =\text{ 0.578 (nearest thousandth)} \end{gathered}`

Hence the Probability of chosen an adult with a high school degree or some college= 0.578
