The following represents the highest educational attainment of all adult
residents in a certain town as shown on the question tab
[tex]\begin{gathered} \text{high school degre = 1414 + 1248 +673 +1042} \\ \text{High school degr}ee\text{= 4477} \end{gathered}[/tex]
[tex]\begin{gathered} \text{Some coll}ege\text{ = 571+704+1076+2773} \\ \text{Some college = 5124} \end{gathered}[/tex]
[tex]\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)} \\ =\frac{4477}{16612}\text{ +}\frac{5124}{16612} \\ =\frac{4477+5124}{16612} \\ =\frac{9601}{16612} \\ =\text{ 0.57796} \\ =\text{ 0.578 (nearest thousandth)} \end{gathered}[/tex]
Hence the Probability of chosen an adult with a high school degree or some college= 0.578
