**Standards: **7.SP.5, 7.SP.6, 7.SP.7, 7.SP.8

**Description:** Students will be learning about probability by shuffling music in the digital music players. This lesson is very adaptable and will have students shuffling their music to discover basic probability, compound probabilities and even experimental vs. theoretical probability. Students will utilize the concepts of probability, theoretical and experimental probability, and using probability to predict to accomplish this.

That doesn’t work. When you divide 1, 120,422 by 8930 you get 125.46719, not 111?

GRRR! Very true – thank you! I will have to change this. I need to stop using my iphone as a calculator – it is too easy to press the wrong button. Very glad you said something, thank you!

And doesn’t that show that it is actually less likely you’ll end up with the same artist in question # 7?

Actually, now that I think about it. It makes sense. Although you are reducing the number of songs overall (the denominator), you’re also reducing the number of songs by your favourite artist, making it less and less likely that one of them will come up. So the odds are better in question 6 that it will come up. They get less likely in question 7.

exactly!
