Renae’s MP3 player can be programmed to randomly play songs from her playlist without repeating a single song. Currently, Renae’s MP3 player has five songs loaded on it which are listed at right. At the moment, she only has time to listen to one song.

  1. Is each song equally likely to be chosen as the first song?

    Yes.

  2. What is the probability that her MP3 player will play a country song?

    The ratio consists of the number of country songs over the total number of songs in the playlist.

  3. What is the probability that Renae will listen to a song with “Mama” in the title?

  4. What is the probability that she listens to a duet with Hank Tumbleweed?

    Refer to hint (b):

  5. What is the probability that she listens to a song that is not R & B?

    Find the number of songs without R&B listed as a genre. Using knowledge from previous steps, formulate a fraction to show the probability of choosing a song without R & B.
