Year 7 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 0. Is it impossible, unlikely, equally likely, likely or certain? Write one of those.
  2. An event has a probability of 0.17. Is it impossible, unlikely, equally likely, likely or certain? Write one of those.
  3. An event has a probability of 0.86. Is it impossible, unlikely, equally likely, likely or certain? Write one of those.
  4. An event has a probability of 0.12. Is it impossible, unlikely, equally likely, likely or certain? Write one of those.
  5. An event has a probability of 0.48. 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 0.5. Is it impossible, unlikely, equally likely, likely or certain? Write one of those.
  8. An event has a probability of 0.61. Is it impossible, unlikely, equally likely, likely or certain? Write one of those.
  9. An event has a probability of 0.93. Is it impossible, unlikely, equally likely, likely or certain? Write one of those.
  10. An event has a probability of 0.64. Is it impossible, unlikely, equally likely, likely or certain? Write one of those.
  11. An event has a probability of 0.47. Is it impossible, unlikely, equally likely, likely or certain? Write one of those.
  12. An event has a probability of 0.43. Is it impossible, unlikely, equally likely, likely or certain? Write one of those.
  13. An event has a probability of 0.51. Is it impossible, unlikely, equally likely, likely or certain? Write one of those.
  14. An event has a probability of 0.35. Is it impossible, unlikely, equally likely, likely or certain? Write one of those.
  15. An event has a probability of 0.91. Is it impossible, unlikely, equally likely, likely or certain? Write one of those.
  16. An event has a probability of 0.13. Is it impossible, unlikely, equally likely, likely or certain? Write one of those.
  17. An event has a probability of 0.29. Is it impossible, unlikely, equally likely, likely or certain? Write one of those.
  18. An event has a probability of 0.78. Is it impossible, unlikely, equally likely, likely or certain? Write one of those.
  19. An event has a probability of 0.87. Is it impossible, unlikely, equally likely, likely or certain? Write one of those.
  20. An event has a probability of 0.57. Is it impossible, unlikely, equally likely, likely or certain? Write one of those.
