Question 1

What is a Card Probability Calculator?

Accepted Answer

Card probability uses the Hypergeometric Distribution to calculate the probability of drawing specific cards from a standard 52-card deck without replacement. Unlike dice (with replacement), each card drawn changes the composition of the deck, making the probabilities hypergeometric rather than binomial.

Question 2

How does the Card Probability Calculator work?

Accepted Answer

Hypergeometric: P(X=k) = C(K,k) × C(N−K, n−k) / C(N,n) Then: N = deck size (52), K = cards of target type, n = hand size, k = desired count Then: C(n,k) = n! / (k! × (n−k)!) — combinations formula Then: P(at least k) = sum of P(X=k) + P(X=k+1) + ... + P(X=K).

Question 3

Can you give an example of how to use the Card Probability Calculator?

Accepted Answer

Example: Input 5-card hand, probability of exactly 1 ace (K=4, n=5, k=1) gives a result of ≈ 34.12% (C(4,1)×C(48,4)/C(52,5)).
