A factory produces 1200 units of a product per day, and each unit has a 5% chance of being defective. What is the expected number of defective units produced per day?
To calculate the expected number of defective units, we simply multiply the total number of units produced by the probability of a unit being defective:

Expected Defective Units = Total Units * Probability of Defect
                        = 1200 * 0.05
                        = 60

So, the factory is expected to produce 60 defective units per day.
