What is the probability of pulling 7 spades in a row from a deck of 52 cards?
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%.
Why cant a guy leave a girl alone when all she wants is peace?
I am in that exact position. I am a girl who just cannot be left alone by boys. Maybe it's because boys tend to flirt with girls, or maybe some boys just don't want to leave girls alone. It's a shame that peace is hard to have in this situation.

The easiest way to think of a complement of a set is what's left over after you take out the given set. For example, if you have the set of all children that attend your local elementary school. Then the complement of all the boys that attend the elementary school would be all the girls that attend the elementary school.
