There are 13 questions in this set. As you go through these questions, use relevant information from previous questions. A manufactured good has two inputs, X is the price of input #1. Y is the price of input #2. These prices are in dollars. Below is the bivariate probability distribution of the prices of these inputs. The covariance between X and Y is 0.4. You will need the covariance later in this set so remember to come back to this value and use it! What is the probability that the price of input #1 will be its smallest value (10)?
