Answer:

1/169

Step-by-step explanation:

The probability of drawing a 3 in a 52 card deck is 4/52 which can be simplified to 1/13.

The probability of then drawing a jack is 4/52, also simplified to 1/13. It doesn't matter of you want to put jack or 3 first, there are 4 of each in a deck.

1/13*1/13=1/169
