QMB3600 cumulative final exam

This document is for review purposes and does not represent every type of problem that may be on the 40 question QMB3600 cumulative final exam.

 

1.         This problem is in reference to students who may or may not take advantage of the            opportunities provided in QMB such as homework.  Some of the students pass the          course, and some of them do not pass. Research indicates that 40% of the students do         the assigned homework. Of the students who do homework, there is an 80% chance            they will pass the course. The probability of not passing if the student does not do the             home   work is 90%.  What is the probability of a student not doing homework or passing?

 

A.        .32

B.        .52

C.        .94

D.        .92

E.         .38

 

2.         Suppose that for a certain football game the probability that the home team will be            ahead at half-time is 0.60 and the probability that the home team will be ahead at half-            time as well as at the final gun is 0.45.  What is the probability that the home team will         win this game given that it is ahead at the half?

 

A.        .45

B.        .75

C.        .15

D.        .27

E.         None of the above.

 

3.         A company markets two products (Product A and Product B) through mail order.  The     company will market them in sequence with the first mail order offer for product A.  It ffeels that there is a 30% chance that any customer will purchase product A. Product B is        offered some months later.  It is felt, for product B, that there is a 30% chance of selling          product B to a customer if the customer purchased product A and a 5% chance of             selling product B to a customer who did not purchase product A.

 

            What is the probability of not selling product B to a particular customer?

33.       Quentin Magic Brown manufactures sports shoes and wants to maximize the company's profits. The company makes two types of sport shoe, Airwalkers and Bouncy Basketball shoes.  The company earns $10 profit on each pair of Airwalkers and $18 profit on each pair of Bouncy Basketball shoes.
The manufacturing process includes cutting the materials on a machine and having workers assemble the pieces.  Each pair of Airwalkers requires 3 minutes of cutting time and the Bouncy Basketball shoes require 2 minutes. The machines that cut the material can run at most 1200 minutes a week.
Each worker takes 7 hours to assemble a pair of Airwalkers and 8 hours to assemble a pair of Bouncy Basketball shoes; the maximum number of hours available is 3500 per week. 
Determine the maximum profit for this problem?
