Probability
Poisson Probability Calculator
Find the probability that exactly k events occur in a fixed interval, given a known average rate λ. Use it for modeling rare events like customer arrivals, server requests, manufacturing defects, or radioactive decay counts.

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.
