Question

In a recent year there were the following numbers (in thousands) of licensed drivers in the United States.Source: World Almanac.Choose one driver at random. Find the following probability of selecting the driver. Round your answers to three decimal places.P (age 21 or female)=

Answer 1

As the probability is about the people who is 21 or female, we have to know how many of these we have.

• People with age 21

$1679+1627=3306$

• Female

$4517+1553+1627=7697$

Now, we have to know the total data:

• Total

$4746+4517+1625+1553+1679+1627=15747$

Finally, to get the probability, we have to divide the data we want by the total data.

$P=\frac{(3306+7697-1627)}{15747}$$P=\frac{9376}{15747}$$P=\frac{9376}{15747}$

Answer:

$P=\frac{9376}{15747}\approx0.595$
