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=((3306+7697-1627))/(15747)`
`P=(9376)/(15747)`
`P=(9376)/(15747)`

Answer:

`P=(9376)/(15747)\approx0.595`
