Well, 52 x 7 = 364.
So, since the year 2020 has 366 days (it's a leap year), we will certainly have 52 full weeks (this is true for a standard 365-day year in fact). Hence, there will be 52 Sundays for certain.
We conclude that P(52 Sundays in the year 2020) = 1.

This question, however, is not really a probability question. It is either going to happen or not, nothing in between really. We can find the possibility of this kind of event by simply counting through the days all the way to the end of 2020 (what I mean is there is no randomness at all involved, so the answer of 1 is not at all surprising).
