Number of Trials (n)
Number of independent trials.
Probability of Success (p)
Probability of success on a single trial (0 to 1).
Number of Successes (k)
Number of successes (0 ≤ k ≤ n).
Calculate
Result: P(X = k) =
Formula:
P(X = k) = C(n,k) * p^k * (1-p)^(n-k), where C(n,k) = n! / (k!(n-k)!)
Calculation:
