Calculadora de probabilidad — Preguntas frecuentes
What is the difference between combinations and permutations?
Combinations (C) count selections where order does not matter. Permutations (P) count selections where order matters. For example, picking 2 from {A,B,C}: C=3 (AB,AC,BC) vs P=6 (AB,BA,AC,CA,BC,CB).
How is the "at least one" probability calculated?
The probability of at least one event occurring in n trials is 1 - (1-p)^n, where p is the probability of a single event.
