Probability
Poisson Probability Calculator
Computes the probability of observing exactly k events in a fixed interval when events occur at a known average rate. Use it for call-centre arrivals, equipment failures, or any count of rare, independent events.

Probability
Coin Flip Probability Calculator
Calculate the exact probability of getting a specific number of heads in a fixed number of fair coin flips. It applies the binomial formula, so it is ideal for statistics homework, game design, and making sense of random streaks.
