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 2 dice are rolled what is the probability of getting a sum greater than 9?
Each die can come up in 6 different ways.
There are (6 x 6) = 36 possible results.
The results that show greater than 9 are:
4 and 6, 6 and 4
5 and 6, 6 and 5
6 and 6, 6 and 6
Six possibilities.
The probability of a sum greater than 9 is [ 6 / 36 ] = 1/6th = 16 and 2/3 percent.
(Odds are 5 to 1 against.)

Find the probability of rolling a sum of 10 with 2 dice?
Well, there are 36 options to be rolled. The only combos that will add up to ten are 5+5 and 6+4. So that's 2 options out of 36. Hence 2/36.
simplified to 1/18 OR 5.56%
What is the probaility of drawing a ace from a deck of cards?
Probability is 4 aces/52 total cards = 1/13 = .07692
What is the probability of obtaining a number that is odd and smaller than 5?
If you are selecting from any number than virtually 0. If you are rolling a die then there are 6 possible outcomes, and 2 numbers that are odd and less than 5 so 2/6=1/3.
Depending on the specifications, it could be 1/4 (25%) or 1/2 (50%). If you specify that Coin A must be heads and Coin B is tails, then it is 25%: Because you have 1/2 chance for each coin, you multiply these chances together : (1/2) x (1/2) = 1/4
However if you just want 'one of the coins' to be heads, and 'the other coin' to be tails, then it is 1/2 (50%). Here are the 4 possible outcomes:
- Both A & B are heads
- Both A & B are tails
- A is heads, B is tails
- A is tails, B is heads.
So for outcomes # 3 & 4 meets our criteria. This is 2 out of the 4 possible, or 2/4 = 1/2 or 50%.
What is the probability that a coin lands on its heads and tails?
The probability of the coin flip being heads or tails is 100%.
What is the theorical probability of rolling a 4 after rolling a number cube 72 times?

What percent of genetic makeup is shared by identical twins?

In these systems, specific outcomes can't be predicted with precision, but the probabilities of given outcomes are known.
What is the probability to roll a 7 or 8 on a eight-sided die?
It depends on what numbers are on its faces.
If it is a fair die with the numbers 1 to 8 - and there is no reason to assume so - the answer is 1/4 or 0.25
What is the probability of the birthday of 6 students fall in exactly 2 calendar months is?
It is not possible to answer the question since births are not uniformly distributed over the year. Furthermore, calendar months are not the same length, either.

What is the probability of getting a king?
What part of the world are you in? If you're talking about the united states replacing the president with a king, that is impossible. There is no probability of the united states getting a king.
Well, what is the question?
If you don't put the first one back in the bag before the second draw, then the total
possible number of draws is (10 x 9) = 90, and only one of them is successful. So the
probability is 1/90 = 0.0111 = 1.11% (rounded).
If you do put the first one back in the bag before the second draw, then the total possible
number of draws is (10 x 10) = 100, and only one of them is the one you want. So the
probability is 1/100 = 0.01 = 1%.

Twins normally skip a generation... but there is no telling until you get a sonogram.
if you DO only have one child at this time, that child has the twin gene, and could have twins.
its the women who determs if you are having twins
