Hi there! I have been working on this problem for quite a while and I keep getting it wrong.

A deck is shuffled and three cards are dealt.

(a) Find the chance that the first card is a king. Give your answer as a fraction.

(b) Find the chance that the first card is a king, the second is a queen, and the third is a jack. Give your answer as a decimal rounded to four decimal places.

So I keep getting half the question right. I got 4/52 for part (a) and for part be I keep getting .0029 for part (b). I am pretty positive part (a) is correct, but now I don't understand part (b) and how I keep getting the answer wrong!

Thank you so much!

a) is correct, you were just concerned about the first card, the others didn't matter

b) Prob(first card is a king) = 4/52 = 1/13
then you want a queen, but one card is gone, so 4/51
and then a Jack ----> 4/50
prob(your event) = (1/13)(4/51)(4/50) = appr .0005
