Step-by-step solution for: Inverse, Converse and Contrapositive Worksheet for 8th - 10th ...
It seems you've described a scenario involving a set of questions or tasks, but the image itself is not provided. However, based on your description, I can infer that the task involves interpreting logical expressions and determining their truth values based on certain conditions. Let me outline a general approach to solving such problems and explain how to interpret the logical expressions.
---
1. Understand the Logical Expressions:
- Familiarize yourself with logical operators such as "and" (`∧`), "or" (`∨`), "not" (`¬`), and implications (`→`).
- Understand the meaning of each operator:
- `A ∧ B`: Both A and B must be true.
- `A ∨ B`: At least one of A or B must be true.
- `¬A`: A is false.
- `A → B`: If A is true, then B must also be true. If A is false, the implication is automatically true.
2. Analyze Each Statement:
- Break down each statement into its components.
- Determine the truth value of each component based on the given conditions.
- Use the rules of logic to evaluate the overall truth value of the statement.
3. Evaluate Implications:
- For implications (`A → B`), remember:
- If `A` is true, then `B` must also be true for the implication to hold.
- If `A` is false, the implication is automatically true regardless of `B`.
4. Consider All Possible Cases:
- If there are variables or conditions that are not explicitly stated, consider all possible scenarios to ensure the solution is comprehensive.
5. Provide Clear Explanations:
- Explain your reasoning step by step, showing how you arrived at the truth value of each statement.

Let's assume one of the questions from your task is as follows:
#### Question:
"If it is raining, then I will stay indoors."
- Symbolically: `R → S`
- `R`: It is raining.
- `S`: I will stay indoors.
#### Conditions:
1. It is raining (`R` is true).
2. I stayed indoors (`S` is true).
#### Task:
Determine whether the statement `R → S` is true or false under these conditions.
#### Solution:
1. Understand the Implication:
- The statement `R → S` means: "If it is raining, then I will stay indoors."
- This is logically equivalent to: "It is not raining, or I will stay indoors" (`¬R ∨ S`).
2. Evaluate the Truth Values:
- Given: `R` is true (it is raining).
- Given: `S` is true (I stayed indoors).
3. Apply the Implication Rule:
- Since `R` is true, for the implication `R → S` to be true, `S` must also be true.
- Here, `S` is indeed true.
4. Conclusion:
- The statement `R → S` is true because the condition "if it is raining, then I will stay indoors" holds under the given circumstances.

Here’s a quick recap of how to evaluate logical expressions:
1. Conjunction (`∧`):
- `A ∧ B` is true if both `A` and `B` are true.
- Otherwise, it is false.
2. Disjunction (`∨`):
- `A ∨ B` is true if at least one of `A` or `B` is true.
- Otherwise, it is false.
3. Negation (`¬`):
- `¬A` is true if `A` is false.
- `¬A` is false if `A` is true.
4. Implication (`→`):
- `A → B` is true if:
- `A` is false, or
- Both `A` and `B` are true.
- `A → B` is false only if `A` is true and `B` is false.
