A manufacturing process for semiconductors has a defect rate of one defect for every thousand components. To compute the probability that there will be at least 10 defective semiconductors in a batch of 6000 semiconductors, select one: a. Approximate the probability by 1- Q 9.5-6 where d is the CDF of N(0, 1) /6*999/1000 b. Approximate the probability by 1 9.5-6 where o is the PDF of N(0, 1) 6*999 /1000 O c. 1- ER-O (20) (2)"( 2)6000-k d. Approximate the probability by 1 - _ e-10 10k ke
