From a standard deck of playing cards, there are 52 cards. There are 13 cards for each Spades, Hearts, Clubs and Diamonds. For the first card, the probability of getting a Spade is 13/52.
If you're going to replace the first card into the deck, then the probability of second card being a Spade is also 13/52
Therefore, 13/52 x 13/52 = 1/16 (one in every sixteen tries)
If you're not going to replace the first card into the deck, the remaining deck will be left with a total of 51 cards and 12 Spades. Therefore the probability of second card being a Spade is 12/51
Lastly, 13/52 x 12/51 = 1/17 (one in every seventeen tries)

What is the probability of not drawing a spade from a standard deck of playing cards?
The answer depends on how many cards are drawn. If you draw 40 cards, the probability is 0. The probability of not drawing a spade in a random draw of one card from a standard deck is 39/52 = 3/4.
What is the probability that a spade or a jack is drawn out of 52 cards?
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.
What is the probability of picking a spade out of a 52 card deck of cards?
One in four. There are 52 cards in the deck; 13 cards in each of four suits. Spades is one of the four suits, so you have one chance in 4 of picking a spade from a shuffled deck.
What is the probability of drawing 2 hearts and then a spade in that order from a deck of 52 cards?
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.
A pack of cards is shuffled and one is drawn out at random 80 times what is the probability of drawing a spade?
Given the way you have worded the question I take it to mean, what is the probability of drawing at least one spade?We can do this most easily by asking first, what is the probability of drawing no spades on each of the 80 times. This is 39/52. The probability of doing this 80 times is (39/52)80.Then the probability of not doing this is 1 - (39/52)80, which is quite close to one. The probability of drawing at least one spade is almost one.
