Write the following in symbols :
If teams do not arrive or the weather is bad, then there will be no match.

Answer

To convert the given statement "If teams do not arrive or the weather is bad, then there will be no match" into symbolic form, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Sub-statements:**
- Let \( P \): Teams do not arrive.
- Let \( Q \): The weather is bad.
- Let \( R \): There will be no match.

2. **Identify the Logical Connectives:**
- The phrase "If... then..." indicates an implication.
- The word "or" indicates a disjunction.

3. **Construct the Disjunction:**
- The statement "teams do not arrive or the weather is bad" can be represented as:
\[ P \lor Q \]
- Here, \( \lor \) represents the logical OR.

4. **Construct the Implication:**
- The entire statement can be expressed as:
\[ (P \lor Q) \implies R \]
- Here, \( \implies \) represents the logical implication.

5. **Final Symbolic Representation:**
- Therefore, the complete symbolic representation of the statement is:
\[ (P \lor Q) \implies R \]

### Final Answer:
\[ (P \lor Q) \implies R \]
