Deck of Cards Probability Question

Question

There are two decks of cards. Each deck has a red, a yellow, a blue, and a green card in it. If a card is drawn, from the first deck, and then a second card drawn from the second deck, what is the probability that a red card and green card are drawn (not necessarily in that order)?

Would you multiply 1/4 by 1/4 to find the answer?

Answer 1

The first card can be red or green, so 1/2

 

The second choice depends on the first, so 1/4

 

1/2 * 1/4 = 1/8
