Q1: What is a p-value in testing hypothesis?

Q2: How does this p-value help us to decide to/not to reject a Null hypothesis? What might happen if we do not use this p-value in particular, when we are rejecting a Null hypothesis?

Q3: What are the limits of these p-values to decide if we have made a right decision on rejecting a false Null hypothesis?
