The answer is 8,648,640 in 674,274,182,400 or approximately 0.128%.
To pull seven spades in a row from a deck of 52 cards may be translated as follows:
In a deck of 52 cards there are 13 spades, so 13 chances to pull a spade or 13/52.
After pulling one spade, there are 12 spades left and 51 cards left, so 12 chances to pull a spade or 12 / 51.
After pulling the second spade, there are 11 spades left and 50 cards left, so 11 chances to pull a spade or 11 / 50.
Continuing the above logic to the natural conclusion, we get the following multipliers:
13 / 52 * 12 / 51 * 11 / 50 * 10 / 49 * 9 / 48 * 8 / 47 * 7 / 46
which is equal to 8,648,640 / 674,274,182,400 or approximately 0.128%.
The probability of drawing the Four of Spades from a standard deck of 52 cards is 1 in 52, or about 0.01923.
there's 13 spades in a standard deck but since we're talkin' two decks.. there's 26 spades out of 104 cards.. so you do 26/104 which reduces to 1:4 aka the probability
1 in 52
There are 52 cards in a deck and 1 ace of spades. So the probability is 1/52 or unlikely.
