If there were fifteen cards left in the deck, and five were diamonds, what is the probability that two cards dealt (without replacement) would both be diamonds?

Answer 1

5/15 * 4/14

Answer 2

How did you get that answer?

Answer 3

there were 15 cards, 5 of them diamonds. So, the chance of getting a diamond is 5/15

After that, having drawn a diamond, there are only 14 cards left, 4 of them diamonds. So, the chance that the 2nd draw is another diamond is 4/14.

Answer 4

If the events are independent, the probability of both/all events occurring is determined by multiplying the probabilities of the individual events.
