🎱 Hypergeometric Distribution: Urn Experiment

The Problem: We have an urn with N balls (M red, N-M green). We draw K balls at once without replacement. What's the probability of getting exactly x red balls?
50
20
10
4

Original Urn

Red: 20 | Green: 30

Sample Drawn

Red: 0 | Green: 0

Probability of exactly 4 red balls:
P(X = 4) = 0.0000

Expected Red Balls

0.00
E[X] = K × M/N

Variance

0.00
Var[X] = K × (M/N) × (1-M/N) × (N-K)/(N-1)

Most Likely Outcome
