日本語: 「成功する」の度合いを客観的に評価する文脈なので、「蓋然性」（確からしさ、見込みの高さ）が適切です。「可能性」も意味は通じますが、よりフォーマルで客観的なニュアンスを持つ「蓋然性」がN1語彙として求められます。
English: In the context of objectively evaluating the 'degree of success,' '蓋然性' (probability, likelihood) is appropriate. While '可能性' (possibility) also conveys meaning, '蓋然性' carries a more formal and objective nuance, making it suitable for N1 vocabulary.
