Question

a company is conducting a survey to determine how prepared people are for a long-term power outage, natural disaster, or terrorist attack. the frequency distribution on the right shows the results. use the table to answer the following question.

what is the probability that the next person surveyed is very prepared?

\

$$\begin{tabular}{|l|c|} \\hline \\textbf{response} & \\textbf{frequency} \\\\ \\hline very prepared & 254 \\\\ \\hline somewhat prepared & 925 \\\\ \\hline not too prepared & 546 \\\\ \\hline not at all prepared & 305 \\\\ \\hline not sure & 60 \\\\ \\hline \\end{tabular}$$

the probability the next person surveyed is very prepared is .
(round to three decimal places as needed.)

Explanation:

Calculate the total frequency

Using the Frequency Distribution knowledge point

$$
LATEXBLOCK0
$$

Calculate the empirical probability

Using the Relative Frequency Calculation knowledge point

$$
LATEXBLOCK1
$$

Round to three decimal places

Using the Relative Frequency Calculation knowledge point

$$ P(\text{Very prepared}) \approx 0.122 $$

Answer:

The probability the next person surveyed is very prepared is <blank>0.122</blank>.
