Suppose that 1% of all computers of a certain type experience cpu failure during the warranty period. if a simple random sample of 500 such computers is taken,
(a) what is the expected value and the standard deviation of the number of computers in sample that experienced cpu failure during the warranty period?
(b) what is approximately the probability that none of the computers in the sample experienced cpu failure during the warranty period? (remark: can you compute the exact value of this probability? )
(c) what is approximately the probability that more than 4 computers in the above sample experience cpu failure during the warranty period?
