Geometric Distribution Calculator
Calculate the probability of first success occurring on the kth trial
About Geometric Distribution
The geometric distribution models the number of trials needed to get the first success in independent Bernoulli trials.
Key Formulas:
- P(X = k) = p(1-p)^(k-1)
- Mean = 1/p
- Variance = (1-p)/p²
Example: How many coin flips until you get heads?
