確率

1. Origins, structure, and basic meaning

• Structure: 確率 is read as かくりつ and is a noun for the probability of an event, often expressed numerically or as a ratio.
• Basic usage: A clause identifies the event in 同じ目が出る確率 or 雨が降る確率.

2. Common pitfalls and similar expressions

• Difference from 可能性
  • 可能性 broadly means possibility or potential; 確率 more strongly presents likelihood as something calculated or quantified.
• High and low probability
  • Degree is normally expressed with 確率が高い or 確率が低い, rather than words for many and few.
