(A) Determine the number of ways that 4 chips can be chosen randomly without replacement from these 30 computer chips. The number of ways that 4 chips can be chosen randomly without replacement from these 30 computer chips is obtained below as follows: The required number of ways is, The number of ways that 4 chips can be chosen randomly without replacement from these 30 computer chips is 27,405.(B) Determine the number of ways in which 4 chips can be chosen randomly with replacement from the defective part of these 30 computer chips. The number of ways in which 4 chips can be chosen randomly with replacement from the defective part of these 30 computer chips is obtained below as follows: The required number of ways is, The number of ways in which 4 chips can be chosen randomly with replacement from the defective part of these 30 computer chips is 40,920.(C ) Obtain the probability that 4 of them are defective. The probability that 4 of them are defective is obtained below as follows: Let X denotes the number of chips are defective which follows binomial distribution with the probability of success 9|30 and the random sample of 6 chips has been selected. That is, The probability that 4 of them are defective is 0.0595.
