Question

in one town 59% of all voters are Democrats if 3 voters are randomly selected for a survey find the probability that all 3 are Democrats

Answer 1

Answer #1

p = 0.59

n = 3

It is a binomial distribution.

P(X = x) = nCx * p^x * (1 - p)^{n - x}

P(X = 3) = 3C3 * (0.59)^3 * (0.41)^0 = 0.2054
