Analyze the following scenario and complete the following:Marketing Research and Data Analysis
- Determine what type of approach should be used to calculate the desired probability: Classical, Empirical, or Subjective.
- Determine the probability of the desired event, if possible, rounding to 3 significant digits.
A chef at a restaurant receives 68 orders during the course of an evening. He made a mistake with 11 of these orders. Based on this, what is the probability that the chef will make an error on the next order he receives?
- Approach:
(click to select) Classical Empirical Subjective
- Probability of error on next draw:
Round to 3 significant digits. Enter 0 if Subjective.
Question 2 of 5
737 people phoned customer support for help with their internet connection. Technicians were not able to provide a solution for 402 of customers who had called.
If one customer is randomly selected from the number of people that phoned:
- Calculate the probability that it’s a customer that technicians were not able to help, rounded to 3 significant digits as needed.
- Calculate the probability of the complementary event.
Question 3 of 5
Complete the following table and use it calculate the probabilities given below.
B | Bc | Total | |
A | 0.434 | 0.258 | |
Ac | |||
Total | 0.553 | 1 |

Question 4 of 5
In a survey that asked 83 people to indicate the reasons why they do not go to the gym, 57 responded that they were too busy, 23 said they felt too tired/lazy to go, and 10 said both.
- If a participant is randomly selected from the study, determine the probability that he/she does not go to the gym because he/she is too busy or because he/she is too tired/lazy.
P (Busy or Tired/Lazy):
Round to 3 significant digits.
- If a participant is randomly selected from the study, determine the probability that he/she does not go to the gym for reasons not related to busyness or tiredness/laziness.
P (Other):
Round to 3 significant digits.
Question 5 of 5
A consulting firm offers a market viability study to businesses seeking to expand into a new market. In the past, when a business experienced expansion success in a new market, the survey had revealed favourable conditions 75% of the time, and when a business did not experience expansion success in a new market, the survey had revealed unfavourable conditions 95% of the time. If 60% of the businesses that expanded experienced success, what is the probability that a business will experience success given a favourable market report from the consulting firm?
