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 chance of selecting a red queen from a pack of 52 cards?
There are 2 red queens, assuming a randomly shuffled deck the chances of any one card being selected is 1 in 52, therefore the chance of either of the red queens being selected is 2 in 52. This is normally shown as 1 in 26.
Who created the deck of cards?
No one actually knows. Playing cards have been around since the early 9th century in China.

What does it mean if a number has a probability of 1?
If a number has a probability of 1 it means it is certain to occur.
The probability is 7/36.
A die is rolled 5 times what is the probability of rolling exactly one 2?
Possible outcomes of rolling a die 5 times = 6^5
Number of outcomes including rolling exactly one 2: 5^5 (5*5^4)
5^5/6^5 = 3125/7776 ~= 0.4019
What is the possible outcome of tossing 10 coins?

If a mother has a son. What is the probability that she will have a girl?
It is not possible to say because the children's genders are not independent.

Experimental Probability: The number of times the outcome occurs compared to the total number of trials.
example: number of favorable outcomes over total number of trials.
Amelynn is flipping a coin. She finished the task one time, then did it again. Here are her results: heads: three times and tails: seven times. What is the experimental probability of the coin landing on heads?
Answer: 3/10
Explanation: Amelynn flipped the coin a total of 10 times, getting heads 3 times. Therefore, the answer is: 3/10.
Head lice, or pediculosis capitis, is caused by an infestation of head lice, peduculis humanus capitis. It is spread by direct head to head contact with an infected person. Transmission by bedding, clothing, or headgear is possible, though less common.
The probability of the mean plus or minus 1.96 standard deviations is 0. The probability that a continuous distribution takes any particular value is always zero. The probability between the mean plus or minus 1.96 standard deviations is 0.95
What is the probability that an ace or black card is drawn from a deck?
28 in 52. Or simplified, 7 in 13.
How does probability relate to camouflage?
the probability relates to camouflage because how much of a color there is
What is the difference between Bayes' Theorem and total Probability?
the n partition of A , in B , so the results of summation of all Ai's probabilities which individually intersect with B divided by probability of B is totals theorem, so simply we say if you want to find the probability of any partition is bays theorem and if you have partitions and wants to find the probability of A is Totals theorem.

What is the probability of rolling a whole number on one roll of a number cube?
Every number on a number cube is a whole number. (A whole number is a number without a fraction or decimal) So the probability of rolling a whole number on a number cube one time would be 6/6 or 1.
The probability is 6/36 = 1/6.
