Verdict
The clearest difference is price: Symbolab at Free against Probability's $1.99. Symbolab also leads on ratings volume (26K vs 193) and update cadence (monthly vs every 3 months). Probability's advantage is review sentiment (97% vs 60%) and in-app purchases (none vs 8). On ads there is nothing between them.

Symbolab is free to download; Probability costs $1.99 up front. Symbolab sells 8 in-app purchases, starting at $2.49 per 7 days. Probability asks for nothing beyond the download.
Probability holds the better App Store score, 4.9 against 4.6. That said, the two scores are not equally well evidenced: Symbolab has 26K ratings behind it against 193, so its average is the more settled of the two.
