There are two black jacks in a set of cards. There are 52 cards in a set.
There is a basic rule in probability that, if all events are equally likely, then the probability of a given event is the number of ways that event can happen, divided by the total number of events.
For example the probability of rolling a three in one dice roll is 1 / 6 because there's one way to roll a three, and 6 possible outcomes. 1 / 6.
So, how many ways can you get a black jack?
And how many outcomes are possible over all?
Then divide the first, by the second.
