Question

use the frequency distribution, which shows the number of american voters (in millions) according to age, to find the probability that a voter chosen at random is in the 18 to 20 years old age range.

\

$$\begin{array}{|c|c|} \\hline \\text{ages} & \\text{frequency} \\\\ \\hline \\text{18 to 20} & 5.7 \\\\ \\hline \\text{21 to 24} & 8.1 \\\\ \\hline \\text{25 to 34} & 20.8 \\\\ \\hline \\text{35 to 44} & 25.2 \\\\ \\hline \\text{45 to 64} & 51.1 \\\\ \\hline \\text{65 and over} & 28.4 \\\\ \\hline \\end{array}$$

the probability that a voter chosen at random is in the 18 to 20 years old age range is .
(round to three decimal places as needed.)

Explanation:

Sum the frequencies

Using the Frequency Distribution knowledge point

$$
LATEXBLOCK0
$$

Calculate the target probability

Using the Empirical Probability knowledge point

$$
LATEXBLOCK1
$$

Round to three decimal places

Using the Empirical Probability knowledge point

$$ P(\text{18 to 20}) \approx 0.041 $$

Answer:

The probability that a voter chosen at random is in the 18 to 20 years old age range is <blank>0.041</blank>.
