From a standard deck of cards, what is the probability that you choose a red card and then a 3, assuming you replaced the first card?

Respuesta :

1/26: 26 red cards make a 1/2 probability, there are 4 3s in a deck, making a 1/13 probability. Considering you don't take the cards and leave them, (1/2)1/13= 1/26
