Dabarar lissafi
P(X = k) = nCk × p^k × (1 − p)^(n − k). Mean = np. Variance = np(1 − p).
Misali da aka warware
With the starting entries (Trials (n): 10, Chance of success each time: 50, Successes (k): 7), the calculator shows p(exactly 7) of 11.7188%. It also reports p(at most 7) 94.5313%; p(fewer than 7) 82.8125%; p(at least 7) 17.1875%; p(more than 7) 5.4687%.
Zato da iyakoki
- Trials are independent with a constant probability.
Kurakuran da aka saba yi
- Using it for draws without replacement from a small group.
- Mixing up exactly da at most.
