Given:
A standard deck of cards consists of four suits (clubs, diamonds, hearts, and spades), with each suit containing 13 cards (ace, two through ten, jack, queen, and king) for a total of 52 cards in all.

Since, there are four Jack in a 52 card deck.
So, one jack can be chosen by 4C1 ways.
Also there are 13 cards of hearts in a 52 card deck.

The number of ways = 4C1 + 13C1 = 4 + 13 = 17.
