Chapter 3: Problem 4

Write the negation of each conditional statement. If the TV is playing, then I cannot concentrate.

Short Answer

Expert verified
The negation of the statement 'If the TV is playing, then I cannot concentrate' is 'The TV is playing and I can concentrate'.

Step by step solution

01

Write the negation

The negation of the statement follows the form 'P and not Q'. Therefore, for the given sentence, the negation would be 'The TV is playing and I can concentrate'.
