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?

How did you get that answer?
Answered by Steve
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.

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