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.

How do you find the probability of an event followed by another event?
If the events are independent then you can multiply the individual probabilities. But if they are not, you have to use conditional probabilities.
If Drawing 3 cards that all queen from a deck of cards?
The probability of drawing three queens from a deck of cards is (4 in 52) times (3 in 51) times (2 in 50), or 24 in 132,600 or 1 in 5,525.
How do you convert percentages into averages?
Are you talking about grades? There are several ways to do this. Ask the teacher how it is done.
What does it mean for probability to be exhaustive?
A set of events is said to be exhaustive if, between them, they cover all possible outcomes.
What is the probability of rolling 5 on regular six sided six?
If you roll the die often enough, the probability is 1 - a certainty.
On a single roll, the probability is 1/6.
If you roll the die often enough, the probability is 1 - a certainty.

Probability of dealing ace king and queen of spades in that order when dealing only 3 cards?
The probability of dealing the Ace of Spades from a normal 52 card deck is 1 in 52. The probability of dealing the King of Spades next is 1 in 51. The probability of dealing the Queen of Spades next is 1 in 50.
The probability of drawing those three cards in that order is the product of those probabilities, which is 1 in 132,600. This is the same as the number of permutations of N (52) things taken P (3) at a time, which is stated as N! - P! (52 * 51 * 50)
If you did not care what order the cards were dealt in, but still wanted to know the probability of getting the Ace, King, and Queen of Spades, then you would be talking about the combinations of N (52) things taken P (3) at a time, which is stated as (N! - P!) / (N - P)! (52 * 51 * 50 / 3 / 2 / 1). The probability in this case is 1 in 22,100.
What is the probability of having a girl or boy child?
Statistically speaking, about 50% for each, but in reality it will depend on the father's genetics and timing of conception, pH level of the mother's body, and maybe even some more stuff.
When two dice are rolled what is the probability that both will be the same number?
6 sides on each dice. Each number on the sides is different, this represents the 1 out of all 6 amounts shown. So this is what you'll do for each dice...
1/6 + 1/6 = 2/6 = 1/3
What does sub standard material mean?
It means that the material does not meet at least one of the requirements in terms of its quality.
How do you increase your chances of having a girl?
girls are actually easier to conceive than boys. girl sperm are generally stronger. sperm counts lessen in men with heat, so tight underwear for men, position; woman on top,
What are the uses of probability in the working world?
It is used in insurance and health care to look at how risky it is to offer a policy to a given person or group. In Las Vegas, it is used in all games. When looking at reactions to medications, people look at the odds that a given person will have an adverse outcome. There are many more, but this gives you an idea.
There are 10 marbles and 5 purple marbles in a bag what are the odds in favor of it being yellow?
6/10 or 3/5
If an identical twin marries an identical twin what is the likelihood of them having twins?
the statistics of twins marrying twins having twin children is only a slight fractional increase in percentage of chance. it is almost negligable however the slight increase has lead many people to believe the common misconseption of twim marraige resulting in the birth of more twins alot.
Yes. And that is true of most probability distributions.
What is the probability that the number rolled will be less than 6?
The probability of rolling a number less than 6 on a die would be 5/6.
The chance is equal to the proportion of people who do not understand the basics of probability. 1 does not represent the chance that "will not the event occor" or, that the event will not occur.
It is incalculable.
