The random variable X represents the number of jurors who oppose the death penalty. A) hypergeometric; N = 34, n = 12, k = 7, x = 0, 1, 2, . . . , 7
B) hypergeometric; N = 34, n = 7, k = 12, x = 0, 1, 2, . . . , 7
C) hypergeometric; N = 34, n = 12, k = 7, x = 0, 1, 2, . . . ,12
D) not hypergeometric
