You have 150 songs on your ipod. the probablity of randomly choosing a country song is 20%. how many of the songs on your ipod are not country songs

In this question, we're trying to find the probability of the songs that are not country songs.

We know that you have a total of 150 songs.

There is a 20% probability of randomly choosing a country song, so let's calculate how many country songs are there.

150 · 0.20 = 30

There are 30 country songs in your iPod.

Now, to see how many songs you have that are not country songs, subtract 30 from 150

150 - 30 = 120

This means that you have 120 songs that are not country songs

120 songs

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you
