Question

Consider drawing cards without replacement from a standard deck of 52 playing cards. Your initial five cards are: 8 9 10 J Q a) What is the probability your 6th drawn card will be a 7, a Q, or a K? b) What is the probability your 6th drawn card drawn will be a ? c) Show that a flush (5 cards with the same suit) is a less probable hand of cards to draw than a straight (5 sequential cards).

Explanation / Answer

a) No of cards left = 47

No of cards of 7, Q,K = 4+3+4 = 11

Probability = 11/47
