Concept explainers
Business Suppose you are the manager of a firm. The accounting department has provided cost estimates, and the sales department sales estimates, on a new product. You must analyze the data they give you, determine what it will take to break even, and decide whether to go ahead with production of the new product. (See Example 7.)
Cost is estimated by

- 11. (a) Define the (mathematical and conceptual) definition of conditional probability P(A|B). (b) Explain the product law in conditional probability. (c) Explain the relation between independence and the conditional probability of two sets.arrow_forward12. (a) Explain tail events and the tail o-field. Give an example. (b) State (without proof) the Kolmogorov zero-one law.arrow_forward14. Define X-¹(H) for a given HER. Provide a simple example.arrow_forward
- 9. Define a 7-system. Show that P = {(0, x]; (0, 1]} is a л-system.arrow_forward25. Show that if X is a random variable and g(.) is a Borel measurable function, then Y = g(X) is a random variable.arrow_forward24. A factory produces items from two machines: Machine A and Machine B. Machine A produces 60% of the total items, while Machine B produces 40%. The probability that an item produced by Machine A is defective is P(D|A)=0.03. The probability that an item produced by Machine B is defective is P(D|B) = 0.05. (a) What is the probability that a randomly selected product be defective, P(D)? (b) If a randomly selected item from the production line is defective, calculate the probability that it was produced by Machine A, P(A|D).arrow_forward
- (c) Show that A is the limit of a decreasing sequence and A, is the limit of an increasing sequence of sets.arrow_forward3. Let A (-1, 1-1) for even n, and A, -(+) for odd n. Derive lim sup A, and lim inf Aarrow_forward1. Let 2 (a, b, c} be the sample space. the power sot of O (c) Show that F= {0, 2, {a, b}, {b, c}, {b}} is not a σ-field. Add some elements to make it a σ-field.arrow_forward
