3) The pharmaceutical company needs to produce 30 kg of active substance X and 10 kg of active substance Y. There are three types of dried herbs. One package of herb A contains 10 g of fabric X, 3 g of fabric Y and the purchase price in CZK has a normal distribution of N(120, 900). One package of herb B contains 15 g of substance X, 4 g of substance Y and the purchase price in CZK has a normal distribution of N(200, 400). One package of herb C contains 30 g of substance X. 15 g of substance Y and the purchase price in CZK has a normal distribution of N(400, 900). A) Formulate the given problem as stochastic programming, denote random variables. B) Transfer to deterministic problem, choose such a criterion that to ensure minimizing fluctuations of profit, when reaching the mean value of maximal 350 thousands of CZK.
