How to say "probable" in Japanese

• ありそうCommon
  na-adjectiveCovers the basic sense of 'probable; likely' — something seems likely to be the case or to happen. It is a casual, conversational way to express likelihood, typically used in everyday spoken judgments about events or outcomes.
  ぼくは興味きょうみありそうな風かぜをした。↗

  I put on an air of interest.
• 濃厚のうこうCommon
  na-adjectiveMeans 'probable' in the sense of a very strong likelihood, especially of a suspicion, sense, or feeling being pronounced. It fits contexts such as strong suspicion that something is the case, rather than casual everyday predictions.
  インサイダー取引いんさいだーとりひきに当あたる疑うたがいが濃厚のうこうになってきた。↗

  Suspicion that this amounts to insider trading has strengthened.

Use 「ありそう」 for the plain everyday sense that something seems likely to happen, and 濃厚 for saying a suspicion, sense, or possibility is strong or very likely.
