Final answer:
When p is a necessary condition for q, it means that p must be true if q is true. In formal logic, this is represented as 'If q, then p' or 'q → p'.
Step-by-step explanation:
Step-by-step explanation:
When we say that 'p is a necessary condition for q,' it means that p must be true if q is true. In other words, p is a requirement for q to be true. This can be represented in formal logic as: 'If q, then p' or 'q → p'.
Example: Let's consider the statement 'If it is raining, then the ground is wet.' Here, we can say that 'it is raining' (p) is a necessary condition for 'the ground is wet' (q). If it is not raining, the ground cannot be wet.
