Question

Problem: The following probability distribution shows a company's monthly demand. X Demand 0 1,000 2,000 3,000 4,000 f(x) Probability 0.10 0.20 0.30 0.30 0.10 1. Determine the expected number of units demanded per month. 2. Each unit produced costs $7.00, and is sold for $9.50. How much will the company gain or lose in a month if they stock the expected number of units demanded but sell 1800 units? 3. What is the probability that the demand will be at least 2,000?
