Assume that you start with a well-shuffled regular 52-card deck (no jokers) and draw 2 cards.
The first card can be either a spade or a diamond, giving you 26 possibilities out of the 52 cards, for a probability of 26/52 or 1/2.
The second card must be of the other desired suit, giving you 13 possibilities out of the 51 remaining cards, for a probability of 13/51.
The total probability is then the product of the two, 1/2 x 13/51 = 13/102, or about 12.74%.
the probibility of drawing a heart diamond or a spaid is a 1/3 chance........
The probability of drawing a spade from a standard deck of 52 cards is 13 in 52, or 1 in 4, or 0.25.
Probability of drawing a spade is 13/52. Probability of also drawing a 6 is 3/39. Therefore it would be 13/52 x 3/39= .0192
The probability of drawing a red spade is zero. There are no red spades in a standard deck.
In order to determine the probability of drawing 2 hearts and then a spade, in that order, from a deck of 52 cards, start by considering the first card. The probability of drawing a heart is 1 in 4. Since you have now reduced the number of hearts and the number of cards in the deck by one, the probability of drawing another heart is 4 in 17. Since you have further reduced the number of cards by one, the probability of drawing a spade is 13 in 50. Multiply these probabilities together, (1/4) (4/17) (13/50), and you get about 0.0153, or about 153 in 10000.

Since you didn't specify the suit of the jack, there are two possible answers. If the jack was a spade, the probability of drawing another spade is 12/51 or 23.5%. If the jack was NOT a spade, the probability of drawing a spade is 13/52 or 25%.
The probability of drawing a red spade is zero. There are no red spades in a standard deck.
The probability of drawing a spade is 1/4 (13/52). The probability of drawing a face card is 3/13 (12/52). The probability of drawing a spade face card is 3/52 (3/52). 13 + 12 - 3 = 22 The probability of drawing a spade or a face card is 11/26 (22/52).

Since you have now reduced the number of hearts and the number of cards in the deck by one, the probability of drawing another heart is 4 in 17.

The probability of drawing a jack is 4 in 52. The probability of drawing a spade is 13 in 52. The probability of drawing a jack or a spade is 4 + 13 - 1 in 52, with the -1 compensating for one of the jacks also being a spade. 4 + 13 - 1 in 52 is 16 in 52, which is also 4 in 13, or about 0.3077.
The probability of drawing a spade in a standard 52 card deck is 13 in 52, or 1 in 4. The probability of drawing a second spade, assuming the first spade was not replaced back into the deck, is 12 in 51. The probability, then, of drawing two spades is the product of those two probabilities, or 12 in 204, or 1 in 17.
Spade: 1 in 4 Ace: 1 in 13
Spade 25% Ace ~8%
The probability of drawing a red card followed by a spade is (1 in 2) times (1 in 4), or 1 in 8, or 0.125. The probability of drawing a spade followed by a red card is (1 in 4) times (1 in 2), or 1 in 8, or 0.125. Since you have two distinct desired outcomes, add them together, giving a probability of drawing a red card and a spade of 0.25.
