Question

Write the contrapositive of the following statement:

‘If the train reaches on time, then I can catch the connecting flight.’

Answer 1

Let p: The train reaches on time.

q: I can catch the connecting flight.

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

Contrapositive: ∼ q → ∼ p is the contrapositive of p → q,

i.e., If I cannot catch the connecting flight, then the train does not reach on time.
