Question 916113: Forty percent of job applicants are rejected in a random sample of 12 applicants, what is the probability that at least 2 are rejected? Answer by ewatrrr(24785) (Show Source):
You can put this solution on YOUR website! Population: p(rejected) = .40
Sample: n = 12,
P(x >= 2) = 1 - binomcdf(12, .40, 1)
0r w/o TI
P(x >= 2) = 1 - P(0) - P(1) = 1 - .60^12 - 12C1(.40)^1(.60)^11
