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.

What is the probability that a ball on a roulette wheel will land on any number from 1 to 12?
There are 38 slots on a roulette wheel, two of them being "0" and "00", and the remainders being all numbers from one to thirty-six inclusive.
This means that your chances of getting any number from 1 to 12 are 12/38, or 6/19, which is is just a bit more than 31.5%
What is probability of throwing 9 heads in a row?
If you toss a coin often enough the probability is 1.
The probability of 9 H in the first 9 tosses is (1/2)9 = 1/512
How many permutations are there for the letters in the word telephone?
The number of combinations of the letters TELEPHONE is 9 factorial, or 362,880. From that, however, we have to divide by 4 to account for the E being repeated twice, so the number of distinct combinations is 90,720.
What is the sample space when tossing 3 coins?
The sample space when tossing 3 coins is [HHH, HHT, HTH, HTT, THH, THT, TTH, TTT]
Yes.
How is the term probability related to genetics?
The term probability is related to genetics because they both give guesses about how something that might be the outcome of something
How many possible outcomes would there be if three coins were tossed up three times?
9, you just have to multiply for problems like this
What is the definition of probability in math?
Probability is the likelihood that some particular event will occur. It is expressed as a number between 0 and 1, where 0 means the event will not occur, and 1 means the event will occur. Values in between 0 and 1 indicate the relative likelihood, i.e. "probability", that the event will occur.
For instance, the probability of tossing heads on a fair coin toss is 0.5, the probability of rolling a 3 on a standard die is 1 in 6, or about 0.1667, and the probability of drawing an ace of spades from a standard deck of 52 cards is 1 in 52 or about 0.01923.
What is the probability that an event will definitely occur?
If the event will definitely occur, then its probability is 1.
Not asked, but answered for completeness sake - if the event will definitely not occur, then its probability is 0. All probabilities lie between 0 and 1, inclusive.

The number of license plates without a repeated letter or digit is 26x25x24x10x9 = 1 404 000. The number of license plates without any restriction is 26x26x26x10x10 = 1 757 600.
Probability of a license plate without a repeated letter or digit = 1 404 000 /1 757 600 = 0.7988
Probability of a license plate with a repeated letter or digit = 1-0.7988 = 0.2022
Which has the best odds lotto Picking 6 out of 52 numbers or picking 5 out of 36 numbers?
The number of combinations of 52 numbers taken 6 at a time is 52 * 51 * 50 * 49 * 48 * 47 / 6 / 5 / 4 / 3 / 2 = 20,358,520. The number of combinations of 36 numbers taken 5 at a time is 36 * 35 * 34 * 33 *32 / 5 / 4 / 3 / 2 = 376,992.
The odds are better with 5 out of 36 numbers, but the payout is probably less as well.
