NAME ___________________________________________________ DATE _____________________ PERIOD __________ Lesson 6 Homework Practice Probability of Simple Events A spinner like the one shown is used in a game. Determine the probability of each outcome if the spinner is equally likely to land on each section. Express each probability as a fraction and as a percent. Then describe the likelihood of the event. Write impossible, unlikely, equally likely, likely, or certain. 1. P(15) 2. P(even) 1 − 16 or 6.25%; unlikely 1 − 2 or 50%; equally likely 3. P(greater than 10) 4. P(perfect square) 3 − 8 or 37.5%; unlikely 1 − 4 or 25%; unlikely A hat contains 8 orange, 20 purple, 9 pink, and 3 brown slips of paper. A slip of paper is selected without looking. Determine the probability of each outcome if it is equally likely to select each slip of paper. Express each probability as a fraction and as a percent. Then describe the likelihood of the event. Write impossible, unlikely, equally likely, likely, or certain. 5. P(pink) 6. P(purple) 7. P(orange) 9 − 40 or 22.5%; unlikely 1 − 2 or 50%; equally likely 1 − 5 or 20%; unlikely 8. P(not brown) 9. P(not purple) 10. P(not pink) 37 − 40 or 92.5%; likely 1 − 2 or 50%; equally likely 31 − 40 or 77.5%; likely 11. P(blue) 12. P(brown) 13. P(not orange) 0 or 0%; impossible 3 − 40 or 7.5%; unlikely 4 − 5 or 80%; likely A spinner labeled 1–8 was spun. The table shows the frequency of each number the spinner landed on. Determine the probability of each outcome if it is equally likely that the spinner landed on each section. Express each probability as a fraction and as a percent. Then describe the likelihood of the event. Write impossible, unlikely, equally likely, likely, or certain. 14. P(4) 15. P(3 or 5) 16. P(not 1) 7 − 40 or 17.5%; unlikely 13 − 40 or 32.5%; unlikely 37 − 40 or 92.5%; likely 17. P(prime) 18. P(odd) 19.
