Acard is chosen at random from a deck of 52 cards. it is replaced, and a second card is chosen. what is the probability that both cards chosen are jacks?

Out of 52 cards 4 are jacks so there is a 4/52 chance the chosen card is a jack

then since the card is put back there are still 4 jacks so there is still a 4/52 chance the second card is a jack

to find the probablility for both cards we need to multiply

4      4
--- × ---   = 0.0059
52    52

the probability that both cards chosen is a jack is 0.0059

I hope I've helped!
