Assuming your deck does not have any joker in it

a: 1 out of 52
b: 2 out of 52 (or 1 in 26)
c: 1 out of 52 also
d: 2 out of 52
e: 1 out of 52
f: no chance at all, all clubs are black
g: yep, again one out of 52
h: 2 out of 52
i: 6 out of 52

if there are jokers, add the number to the total of 52, with 2 jokers, the probability to get the king of heard would be 1 in 54.

I guess that if you always drawn a card the probability is
1/the number of cards in the deck (I guess is 52)

I'm not sure but I think this are the answers

a) 1/# of cards in the deck
b) 2/# of cards in the deck (because you can get the kind of hearts or the kind of diamonds
c) 1/ # of cards in the deck
d) 2/# of cards in the deck (because you can get the jack of clover or the jack of clubs)
e) 1/# of cards in the deck
f) 0 (no red clubs... only blacks)
g) 1/# of cards in the deck
h) 2/# of cards in the deck (because you can get the 2 of clover or the 2 of clubs)
i) you have to count the number of red cards (maybe you can count 2 cards per number) / # of cards in the deck

a) 1/52 (there is only one king of hearts out of 52 cards)
b) 2/52 = 1/26 (there are two red kings out of 52 cards)
c) 1/52 (there is only one king of clubs out of 52 cards)
d) 2/52 = 1/26 (there are two black jacks out of 52 cards)
e) 1/52 (there is only one 10 of diamonds out of 52 cards)
f) 0 (there are no red clubs in a standard deck)
g) 1/52 (there is only one 2 of spades out of 52 cards)
h) 2/52 = 1/26 (there are two black twos out of 52 cards)
i) 6/52 = 3/26 (there are six red picture cards, king-queen-jack of each hearts and diamonds)
