Question

For his lunch, David is making a sandwich that must consist of bread, cheese, and meat. David can choose from white, French or rye bread, either American or Swiss cheese, and the choice of turkey, ham or pastrami as a meat. Create a tree diagram to represent the combinations of bread, cheese, and meat David could make for his sandwich. 4. Joel has an MP3 player called the Jumble. The Jumble randomly selects a song for the user to listen to. Joel's Jumble has 2 classical songs, 13 rock songs, and 5 rap songs on it. What is the probability that the first song that Joel hears is a rap song?

Answer 1

4. You total the songs to find out how many possibilities all together = 20

Then how many of those are rap songs = 5

So the probability of getting rap songs is 5/20 or (simplified) 1/4
