Calculates the probability that at least two people in a group share the same birthday.

Generates random numbers within a specified range.

Calculates the probability of different outcomes when rolling multiple dice.

Calculates probabilities for various outcomes of multiple coin flips (e.g., exactly k heads).

Calculates the number of permutations (arrangements) of a set of items, where the order of selection matters.

Calculates the number of combinations (nCr) - the number of ways to choose k items from a set of n items, where order doesn't matter.

Calculates odds and probabilities, converting between the two and determining odds from event counts.

Calculates conditional probability using Bayes' Theorem, updating probabilities based on new evidence.

Calculates the probability of an event occurring given that another event has already occurred.

Performs arithmetic operations (add, subtract, multiply, divide) on binary numbers.
