Frequently Asked Questions About Probability Calculator
Common questions about our probability calculator
What types of probability calculations can the Probability Calculator perform?
Our calculator can calculate simple probabilities, compound probabilities (AND, OR), conditional probabilities, combinations, permutations, binomial probabilities, and probabilities for various probability distributions.
How does the Probability Calculator calculate simple probability?
For simple probability, the calculator uses the formula 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 the calculator handle combinations and permutations?
Yes! The calculator can compute combinations (C(n,r) = n! / (r!(n-r)!)) and permutations (P(n,r) = n! / (n-r)!) for selecting items from a set, showing factorial calculations and simplification steps.
How does the calculator handle conditional probability?
For conditional probability P(A|B), the calculator uses the formula 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 the calculator compute binomial probabilities?
Yes! The calculator can calculate binomial probabilities using the formula P(X=k) = C(n,k) × p^k × (1-p)^(n-k), showing how to combine combinations with probability calculations.
Is the Probability Calculator free to use?
Yes! Our Probability Calculator is completely free to use. Calculate probabilities for unlimited scenarios without any cost or registration required.
