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
