Probability
The probability of a certain event is a number expressing the likelihood that a specific event will occur, expressed as the ratio of the number of actual occurrences to the number of possible occurrences. In mathematics, it is a measure of how often an event will happen and is the basis of statistics.

When there is a 40 percent chance of rain - what does that mean?
There needs to be a location as well as a time interval.
A statement such as "there is a 40% chance that it will rain in Yourtown over the 12 hours starting at sunrise tomorrow" means that if you consider a whole lot of days like tomorrow - with the same sort of weather as you experienced over the last few days - then in 4 days out of 10 (40%), it will rain tomorrow.
Just to complicate matters, the statement does not distinguish between there being a 40% probability that it will rain non-stop or that it will rain briefly.
What is the possibility of rolling a three if you roll 4 dices at the same time?
You can't, can you? The smallest number that you can roll with four dice is four, that is, a 'one' on each of the four dice.
What is the porbability of choosing a king from a standard deck of plying cards?
The probability of choosing a king from a standard deck of playing cards is 4 out of 52, or 1 out of 13. This is because there are 4 kings (one each of hearts, diamonds, clubs, and spades) in a deck of 52 cards.
How many different three-letter initials are there that begin with an A?
teshome hambissa
first space filled with A this implies that n(first)=1.
second space filled with all letters from a-z this implies that n(second)=26.
third space filled with all letters from a-z this implies that n(third)=26.
therefore by principle of counting
1x26x26=676.

What is the probability of getting at least 3 tails when tossing a coin six times?
Because a coin is two-sided, 50/50 is always the probability. Unless your coin lands on the grass (on the lawn), then it will probably land on its edge.

What happens if you cant mill any cards because you've drawn your last card?
Nothing, you just mill all the remaining cards. The game is only lost when you are told to draw a card, but can't. Effects that put cards in your library into the graveyard, cannot make you lose on their own.
How many ways can you arrange 2 letters in a given word?
Given two letters, there are two ways to arrange them; first then second, or second then first. The way the question is worded, the other letters of the word do not matter.
If you roll a fair six sided number cube what is the probability of rolling an eight?
Assuming that the die is a regular 1 - 6 die, there is zero chance of you throwing an eight with a single six-sided die.
The probability is 0.277... (repeating).
What is the sample space for a spinner spun three times?
The sample space for a spinner spun three times consists of all possible outcomes from each spin. If the spinner has ( n ) distinct sections, then each spin has ( n ) possible outcomes. Therefore, for three spins, the sample space will contain ( n^3 ) outcomes, representing every combination of the results from the three spins. For example, if the spinner has 4 sections labeled A, B, C, and D, the sample space would include outcomes like (A, A, A), (A, A, B), ..., (D, D, D).
What is the total number of eyes pictured on all the face cards in a standard deck of cards?

From what I have been told twins are hereditary through the female line.
No, the amount of proof needed for detention and for going to trial is different. For detention, the probable cause standard is relatively low and requires enough evidence to establish a reasonable belief that a crime has been committed. On the other hand, to go to trial, a higher standard of proof, such as beyond a reasonable doubt, is typically required to establish guilt.
No, it is the same.
