    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

    Answer:

    120 songs
