2) A pharmaceutical factory has 8 contacts for the wholesale of medicine, and the company believes that for each contact the probability of making a sale is A%. Find the probability that the company makes: a. Find the probability that the factory makes at least two sales. b. Find the probability that the factory makes no sale. C. Find mean, and variance.
