Total number of items N
Number of distinct items m
Number of items picked n
Number of distinct items picked k
Probability exactly k distinct items are picked P(X=k)
Probability less than k distinct items are picked P(X<k)
Probability more than k distinct items are picked P(X>k)
Probability less than or equal to k distinct items are picked P(X≤k)
Probability more than or equal to k distinct items are picked P(X≥k)
Mean μ
Example: A deck of 52 (N) cards has 4 (m) red cards. If we draw 5 (n) cards, what are the odds exactly 1 (k) of them will be red?
