QUESTION 1 A retailer of Christmas trees has estimated the mumber of trees that he will sell during the next season. The folowing table summarizes the demands for trees and their respective probabilities: Demand X Probability 0.5 0.2 10 0.3 1.1. Is demand for trees a proper probability function? Why, or why not? 1.2. What is the probability that the demand for trees will be equal to 4? 1.3. What is the probability that the demand for trees will be equal to 10? 1.4. What is the probability that the demand for trees will be greater than 4? 1.5. What is the expected value of demand for trees? 1.6. What is the variance of the demand for trees?
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.

Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
