Use 「可能性」 for whether something can or will happen. Pick 「確率」 for a numeric probability, 「公算」 for likelihood in news reports, 「見込み」 for a forecast, and 「ポテンシャル」 for unrealized potential. 「プロバビリティー」 and 「蓋然性」 are academic, 「蓋然」 is mostly seen in philosophy and logic, 「蓋然率」 is an older term, 「ポシビリティ」 is rare, and 「確からしさ」 also covers credibility. The opposite is 「不可能」.
