Question

The pie-chart above shows the distribution of registered voters, by age, for a community. Registered voters are randomly selected from this distribution to be called for jury duty. What are the odds (in the age range:not in the age range) that the first person called for jury duty is in the age range of 25-35 years?

• A. 1:3
• B. 7:8
• C. 7:43
• D. 21:29
• E. 42:25

Answer 1

The correct option is D 21:29

$\Rightarrow$ Distribution of Registered voters by Age range $25-35=42\%$

$\Rightarrow$ Distribution of Registered voters not in Age range $25-35=100\%-42\%=58\%$

$\Rightarrow$ Required ratio $=\frac{42\%}{58\%}=\frac{21}{29}$
