Frequently Asked Questions About Probability Calculator

Common questions about our probability calculator

What types of calculations are available?

The platform can calculate simple probabilities, compound probabilities (AND, OR), conditional probabilities, combinations, permutations, binomial probabilities, and probabilities for various distributions.

How is simple probability calculated?

For simple probability, the platform uses P(A) = number of favorable outcomes / total number of possible outcomes. It shows how to count outcomes and perform the division step by step.

Can it handle combinations and permutations?

Yes! The platform can compute C(n,r) = n! / (r!(n-r)!) and P(n,r) = n! / (n-r)! for selecting items from a set, showing factorial calculations and simplification steps.

How is conditional probability handled?

For conditional probability P(A|B), the platform uses P(A|B) = P(A and B) / P(B). It shows how to calculate the joint probability and divide by the probability of the condition.

Can it compute binomial probabilities?

Yes! The platform can calculate binomial probabilities using P(X=k) = C(n,k) × p^k × (1-p)^(n-k), showing how to combine combinations with probability calculations.

Is there a cost?

No! The platform is completely free to use. Calculate probabilities for unlimited scenarios without any cost or registration required.
