A standard deck of cards contains 52 cards, of which 26 are red and 26 are black, 13 are of each suit (diamonds, hearts, clubs, spades) and of which 4 are of each domination
(Ace, 1,2,3,4,5,6,7,8,9,10,jack,queen and king).
In this we have 13 of the 52 cards are clubs;
The probabilty is the number of favourable outcomes to the total possible outcomes.
The probabilty of selecting club card on the first draw;
After one club card is selected, now we are left with 12 cards of clubs and 51 cards in total (without replacement -> not putting back the drawn card)
Now probabilty of selecting again clubs;
So probabilty that the two clubs are drawn
If you like the answer please give THUMBS UP.
Thank you.

Suppose two cards are drawn without replacement from an ordinary deck of 52 cards, find the probability of the following results. A 10 and a 2 are drawn. The second is a king given that the first is not a king Two diamonds are drawn. Are the events of drawing two diamonds independent?
We are drawing two cards without replacement from a standard 52-card deck. Find the probability that we draw at least one ten. The probability is (Type an integer or a simplified fraction.)

Two cards are randomly drawn (without replacement) from an ordinary deck of 52 play- ing cards. Let W be the number of aces obtained in the first draw, and Z be the number of pairs obtained in the two draws. a) Find the joint probability mass function of W and Z b) Are W and Z independent? Please justify your answer.
