Hypergeometric Distribution
Compute the following probabilities by using the hypergeometric formula.
a. The probability of x = 2 if N = 11, A = 8, and n = 4
b. The probability of x < 2 if N = 12, A = 5, and n = 6
c. The probability of x = 0 if N = 9, A = 2, and n = 3
d. The probability of x > 4 if N = 20, A = 5, and n=7
(Round your answers to 4 decimal places, e.g. 0.2153.)
a. P(x=2 | N = 11, A = 8, n = 4) =
b. P(x < 2 | N = 12, A = 5, n = 6) =
c. P(x=0|N=9,
A = 2, n = 3) =
