1. 1.Weather systems are stochastic — we can model probabilities, but precise long-range prediction remains impossible. (randomly determined)
2. 2.Large language models are trained using stochastic gradient descent, updating parameters with random data batches rather than the full dataset. (probability-based)

• random/ˈrændəm/— happening without pattern
• probabilistic/ˌprɒbəbɪˈlɪstɪk/— based on probability
• non-deterministic— not having a single predictable outcome

from Greek "stokhastikos" (able to guess) — from "stokhazesthai" (to aim at, to guess) — from "stokhos" (target) — aiming at a target you can estimate but never hit exactly
