What does it mean?
A p-value is the probability, under the null hypothesis and test assumptions, of a test statistic as extreme as or more extreme than the observed one.
Think through an example.
An everyday example
A comparison gives p=0.03. This does not mean the null hypothesis has a 3% probability of being true.
Test your understanding.
