Choosing the right word

  • 可能性かのうせいCommon
    nounCovers likelihood in its most general sense: the chance that something may happen or be the case. Typical context: ordinary discussion of whether something could occur, saying the likelihood is high, low, or slight.

  • 見込みみこみJLPT N1approx.Common
    nounCovers likelihood as a chance judged from the present situation — the prospect or expectation that something will happen. Typical context: schedules, forecasts, and estimates such as chances of recovery or completion.
    そんな計画けいかくはほとんど成功せいこうする見込みこみはありません。↗

  • おそれJLPT N1approx.Common
    nounNot a neutral word for likelihood: it really means the risk or fear that something bad may happen, and is usually written in kana. Typical context: weather and disaster warnings.

Use 確率 for probability as a measure, 可能性 for the general chance that something may happen, 「見込み」 for expected prospects, 公算 for likelihood in forecasts and assessments, and 「おそれ」 only when the outcome feared is bad.
