For the following two demand functions, compute the four partial elasticities of demand and state whether the two commodities are substitutes of complements and the type of good(normal) given that Q1, Q2, P1, P2 > 0. Q1 = 7 – 2P1 – P2 Q2 = 23 – P1 + 3P2

Successful implementation of a new system is based on three independent modules. module 1 works properly with probability 0.96. for modules 2 and 3, these probabilities equal 0.95 and 0.90. compute the probability that at least one of these three modules fails to work properly.
