Question

a person is selected at random for jury duty from a list of registered voters from three different counties. county a has 13,369 registered voters, county b has 15,422 registered voters, and county c has 23,142 registered voters. what is the probability that the person chosen is from county c?
note: for any final answer that has up to four decimal places, enter your answer without rounding the number. for any answers with more than four decimal values, round your final answer to four decimal places.

question 5
the data:
which is represented in the following table, were derived from a study of the effectiveness of a flu vaccine. the value in each cell of the table represents the number of individuals in that category. some participants in the study were given no vaccine, some were given one injection, and some were given two injections.

Explanation:

Step1: Calculate total number of voters

Total voters \(=13369 + 15422+23142\)
\(=51933\)

Step2: Calculate probability for county C

Probability \(P=\frac{\text{Voters in County C}}{\text{Total voters}}\)
\(P = \frac{23142}{51933}\)
Using a calculator, \(P\approx0.4456\)

Answer:

\(0.4456\)
