Verdict
The clearest difference is price: Binomial Coefficient Calc at Free against Probability's $1.99. Binomial Coefficient Calc also leads on update cadence (every 3 weeks vs every 3 months) and device support (3 vs 1). Probability's advantage is in-app purchases (none vs 8) and chart position (#136 vs unranked). On ads there is nothing between them.
