In a binomial distribution that consists of 5 independent trials the probability of getting I and 2 are 0. Then calculate the parameter p of the arrangement. An experiment is performed 4 times, twice as often as it fails and succeeds. Then find out the probability that in next five trials there will be i three successes, ii at least three successes? A quality control engineer checks a random 3 calculators randomly from each bundle of 20 calculator.

Now if each bundle contains 4 slight defective calculators. A batch that is accepted if a sample of five 5 bolts taken from the same batch that contains no defective. The rejected sample contains 3 three or more defectives. In other cases, a second sample is taken. What is the probability that the second sample is required? If probability of a defective bolt is just 0.
