If you have a deck of cards with NO face cards what is the p of picking a king?

I would assume the P is zero. Is there a technical math term for this? Or would zero suffice?

If there is a room of 20 people what is the probability that at least two of them will share the same bday? I know that i can do 364/365 * 363/365, etc... and then subtract that answer from one (to find the complement). However, my calculator will not show such large numbers. Can i some how use factorials to figure this out? I don't know how to make it stop after about 19 or 20 numbers though. I don't want 364!

Any simple way to figure out this prob would be greatly appreciated. Thanks!

3 people need to share a room for the night. Motel owner says the cost is $30. Each person pays $10. Later, owner realizes he should've only charged $25. He sends his son to the room with 5 $1 bills. Son can't figure how to divide $5 three ways, so he gives each person $1 making their net cost $9 each and pockets the $2. Question: 3X$9=$27 + $2 boy pockets = $29. What happened to the other $1?

If you take in to account the number of sperm manufactured, only one gets in the egg. Every sperm and egg combination makes a completely different being. Now factor in all of the decisions made that led to the fertilization, combined with the odds that led to those decisions. Compounded by the split-second timing of everyday decision making (right or left? short or tall? brunette or blond? etc.) Plus, the series of events that created the universe, can the number even be calculated, and does that number exceed the laws of randomness, proving that it could not have happened ANY other way?

Sorry for the abreviation in the title, the whole sentence wouldn't fit. Here is the original question:
Why is the difference between two numbers made by a different combination of the same digits, always equal to a multiple of 9? In other words: choose a number at random, then shuffle the digits in it to make a second number. Subtract the smaller number from the higher one. The result is ALWAYS a multiple of 9. (you can find this by adding all the digits in the number, and the sum will also be a multiple of 9). Why does this happen?
.
I found this out due to this "mind reader":

Thanks!

i want to know how the solution comes for the following:
if x cosA/a + y sinA/b=1, and x sinA/a - y cosA/b=1, prove that x square/a square+ysquare/bsquare=2. i hope you understood what "square" meant. if you didn't, then here's the explanation :2 square= 4. i didn't know to insert the exponent. so please adjust as the question is correct.

If the answer is no, then please copy this question to two other categories. People may be submitting answers thinking the guest quesion asker is actually reading each question.

Suppose you throw a baseball straight up at a velocity of 64 feet per second. A function can be created by expressing distance above the ground, s, as a function of time, t. This function is s = -16t2 + v0t + s0
•16 represents 1/2g, the gravitational pull due to gravity (measured in feet per second2).
•v0 is the initial velocity (how hard do you throw the object, measured in feet per second).
•s0 is the initial distance above ground (in feet). If you are standing on the ground, then s0 = 0

Two perfect logicians, S and P, are told that integers x and y have been chosen such that 1 < x < y and x+y < 100. S is given the value x+y and P is given the value xy. They then have the following conversation.

P: I cannot determine the two numbers.
S: I knew that.
P: Now I can determine them.
S: So can I.

Given that the above statements are true, what are the two numbers?
