If 2 cards are drawn without replacement from an ordinary 52 card deck, find the probability that the first card drawn is a king and that the second card is drawn a king.
I think the answer is 3/51, am I right?
thanks.

Not quite. The probability that the first card is a king is 4/52. Having drawn a king first, the probability of drawing another king on the second draw is 3/51. Therefore the required probability is:
$$\large P(2\ kings)=\frac{4\times3}{52\times51}=you\ can\ calculate$$

no way that is correct, sorry

The result of the calculation is 1/221 or alternatively 0.004525.
That solution is definitely correct for the question exactly as you posted it.
