Year 8 maths · 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 20%. Is it impossible, unlikely, equally likely, likely or certain? Write one of those.
  2. An event has a probability of 100%. Is it impossible, unlikely, equally likely, likely or certain? Write one of those.
  3. An event has a probability of 40%. Is it impossible, unlikely, equally likely, likely or certain? Write one of those.
  4. An event has a probability of 0%. Is it impossible, unlikely, equally likely, likely or certain? Write one of those.
  5. An event has a probability of 50%. Is it impossible, unlikely, equally likely, likely or certain? Write one of those.
  6. An event has a probability of 14%. Is it impossible, unlikely, equally likely, likely or certain? Write one of those.
  7. An event has a probability of 84%. Is it impossible, unlikely, equally likely, likely or certain? Write one of those.
  8. An event has a probability of 97%. Is it impossible, unlikely, equally likely, likely or certain? Write one of those.
  9. An event has a probability of 90%. Is it impossible, unlikely, equally likely, likely or certain? Write one of those.
  10. An event has a probability of 44%. Is it impossible, unlikely, equally likely, likely or certain? Write one of those.
  11. An event has a probability of 43%. Is it impossible, unlikely, equally likely, likely or certain? Write one of those.
  12. An event has a probability of 2%. Is it impossible, unlikely, equally likely, likely or certain? Write one of those.
  13. An event has a probability of 53%. Is it impossible, unlikely, equally likely, likely or certain? Write one of those.
  14. An event has a probability of 54%. Is it impossible, unlikely, equally likely, likely or certain? Write one of those.
  15. An event has a probability of 19%. Is it impossible, unlikely, equally likely, likely or certain? Write one of those.
  16. An event has a probability of 51%. Is it impossible, unlikely, equally likely, likely or certain? Write one of those.
  17. An event has a probability of 58%. Is it impossible, unlikely, equally likely, likely or certain? Write one of those.
  18. An event has a probability of 56%. Is it impossible, unlikely, equally likely, likely or certain? Write one of those.
  19. An event has a probability of 47%. Is it impossible, unlikely, equally likely, likely or certain? Write one of those.
  20. An event has a probability of 6%. Is it impossible, unlikely, equally likely, likely or certain? Write one of those.
