### Probability and Statistics Exercise

**Part 3 of 6:**
- **Question:** The probability that the wafer is from Lot A and is nonconforming is:
- **Answer:** 0.0245

This part likely investigates the combined probability of two events: the wafer being from Lot A and the wafer being nonconforming.

**Part 3 of 6:**
- **Question:** The probability that the wafer is nonconforming given that it is from Lot A is:
- **Answer:** 0.0245

This part explores the conditional probability, specifically the likelihood that the wafer is nonconforming under the condition that it comes from Lot A.

**Part 4 of 6:**
- **Question:** The probability that the wafer is nonconforming given that it is from Lot A is:
- **Answer:** 0.0245

Similar to the previous part, this question examines the conditional probability of the wafer being nonconforming, given it is from Lot A.

**Part 5 of 6:**
- **Question:** The probability that the wafer is from Lot A given that it is nonconforming is:
- **Answer:** 0.0245

This question shifts focus to the Bayesian probability, determining the likelihood that a wafer is from Lot A, given that it is nonconforming.

**Part 6 of 6:**
- **Question:** The events \(E_1\) and \(E_2\) are [Select from a dropdown] independent.
- **Answer:** not

In this part, the question addresses the independence of two events. It concludes that \(E_1\) and \(E_2\) are **not** independent.

#### Diagrams and Graphs Explanation

For this particular image, no diagrams, graphs, or charts were provided. The detailed progression bars visible on each part indicate progress tracking, showing how far along the user is within the transition from part 3 to part 6.

**Note for Teachers:**
When explaining these concepts, consider utilizing visual aids like Venn diagrams or probability trees to better illustrate conditional and Bayesian probabilities. Examples for independent and dependent events can further elucidate the definitions and differences in practice.

### Quality Control in Semiconductor Wafers

#### Overview
A population of 611 semiconductor wafers is sorted into three lots. The wafers are categorized by lot and by whether they conform to a thickness specification. The table below provides data on the number of wafers in each category. A wafer is chosen at random from the population.

#### Data Table
| Lot | Conforming | Nonconforming |
|-----|------------|---------------|
|   A |         97 |            15 |
|   B |        166 |            41 |
|   C |        254 |            38 |

#### Questions
(a) What is the probability that the wafer is from Lot A?
(b) What is the probability that the wafer is nonconforming?
(c) What is the probability that the wafer is from Lot A and is nonconforming?
(d) Given that the wafer is from Lot A, what is the probability that it is nonconforming?
(e) Given that the wafer is nonconforming, what is the probability that it is from Lot A?
(f) Let \(E_1\) be the event that the wafer comes from Lot A, and let \(E_2\) be the event that the wafer is nonconforming. Are \(E_1\) and \(E_2\) independent?

#### Answers and Explanations

**Part 1:**
*Question*: What is the probability that the wafer is from Lot A?
*Answer*: The probability that the wafer is from Lot A is \(\frac{112}{611} \approx 0.1833\).

**Part 2:**
*Question*: What is the probability that the wafer is nonconforming?
*Answer*: The probability that the wafer is nonconforming is \(\frac{94}{611} \approx 0.1538\).

**Part 3:**
*Question*: What is the probability that the wafer is from Lot A and is nonconforming?
*Answer*: The probability that the wafer is from Lot A and is nonconforming is \(\frac{15}{611} \approx 0.0245\).

**Part 4:**
*Question*: Given that the wafer is from Lot A, what is the probability that it is nonconforming?
*Answer*: The probability that a wafer is nonconforming given that it is from Lot A is \(\frac{15}{112
