Likelihood of events from fraction probabilities

Grade 7 math · Fieldbook Learning

Name ______________________ Date __________

Probabilities run from 0 (impossible) to 1 (certain). Write one of the five words.

  1. An event has a probability of 43/100. Is it impossible, unlikely, equally likely, likely or certain? Write one of those.
  2. An event has a probability of 43/50. Is it impossible, unlikely, equally likely, likely or certain? Write one of those.
  3. An event has a probability of 3/5. Is it impossible, unlikely, equally likely, likely or certain? Write one of those.
  4. An event has a probability of 73/100. Is it impossible, unlikely, equally likely, likely or certain? Write one of those.
  5. An event has a probability of 1/2. Is it impossible, unlikely, equally likely, likely or certain? Write one of those.
  6. An event has a probability of 1. Is it impossible, unlikely, equally likely, likely or certain? Write one of those.
  7. An event has a probability of 0. Is it impossible, unlikely, equally likely, likely or certain? Write one of those.
  8. An event has a probability of 93/100. Is it impossible, unlikely, equally likely, likely or certain? Write one of those.
  9. An event has a probability of 59/100. Is it impossible, unlikely, equally likely, likely or certain? Write one of those.
  10. An event has a probability of 49/100. Is it impossible, unlikely, equally likely, likely or certain? Write one of those.
  11. An event has a probability of 19/25. Is it impossible, unlikely, equally likely, likely or certain? Write one of those.
  12. An event has a probability of 11/25. Is it impossible, unlikely, equally likely, likely or certain? Write one of those.
  13. An event has a probability of 23/50. Is it impossible, unlikely, equally likely, likely or certain? Write one of those.
  14. An event has a probability of 97/100. Is it impossible, unlikely, equally likely, likely or certain? Write one of those.
  15. An event has a probability of 7/25. Is it impossible, unlikely, equally likely, likely or certain? Write one of those.
  16. An event has a probability of 69/100. Is it impossible, unlikely, equally likely, likely or certain? Write one of those.
  17. An event has a probability of 8/25. Is it impossible, unlikely, equally likely, likely or certain? Write one of those.
  18. An event has a probability of 2/5. Is it impossible, unlikely, equally likely, likely or certain? Write one of those.
  19. An event has a probability of 9/10. Is it impossible, unlikely, equally likely, likely or certain? Write one of those.
  20. An event has a probability of 1/10. Is it impossible, unlikely, equally likely, likely or certain? Write one of those.
