Generates random numbers within a specified range.

Calculates terms, sum, or formula for a geometric sequence.

Calculates the probability of single or multiple independent events occurring.

Calculates the volume, surface area, and diagonal of a cube based on the length of one side.

Calculates the sides of a 30-60-90 right triangle given one side length.

Demonstrates the counter-intuitive solution to the Monty Hall probability puzzle. This calculator helps visualize the probabilities of winning by switching doors versus staying with the initial choice.
