HOMEWORK
For questions 1-3, use the following information:
A bag contains 5 yellow marbles, 2 blue marbles, and 3 green marbles.
Find each probability as a fraction, reducing as necessary.
1. P(blue marble)
2. P(green or yellow marble)
3. P(yellow and blue)
For questions 4-8, use the spinner shown. Write each probability as both a fraction and a percent.
4. P(1)
6. P(even number and 1)
5. P(2 or 3)
7. P(not 4)
8. P(3 and 4)
