Solution

Given statement is "It is cold and raining."

Let p : It is cold.
q : It is raining.

Then the symbolic form of the given statement is p ∧ q.

The negation of a statement is the opposite truth of given statement and denoted by symbol ∼. 

Since ∼ (p ∧ q) ≡ ∼ p ∨ ∼ q, the negation of the given statement is:
