How often the value of a random variable is at or below a certain value.?
The probability of a random variable being at or below a certain value is defined as the cumulative distribution function (CDF) of the variable. The CDF gives the probability that the variable takes on a value less than or equal to a given value.
How do you find the probability density function?
The probability density function of a random variable can be either chosen from a group of widely used probability density functions (e.g.: normal, uniform, exponential), based on theoretical arguments, or estimated from the data (if you are observing data generated by a specific density function). More material on density functions can be found by following the links below.
What is the difference between a probability mass function and a probability density function?
The probability mass function is used to characterize the distribution of discrete random variables, while the probability density function is used to characterize the distribution of absolutely continuous random variables.

What is the probability of drawing below a five in a deck of cards?
The answer depends on whether the card(s) are drawn at random, whether it is a standard deck (or a pinochle deck), how many cards are drawn, if more than one then whether they are replaced before the next one is drawn. If 40 cards are drawn, without replacement, from a standard deck of cards, the probability of a card below 5 is 1: that is, a certainty. For a single random draw from a standard deck, the probability is 3/13 (Aces high) or 4/13 (Aces low).
What is the signifance of the mean of a probability distribution?
It is the average of all the numbers in the distribution. If you chose a random data point of the distribution, there would be a 50% chance that it is above the mean, and a 50% chance that it is below the mean.
How often the value of a random variable is at or below a certain value?
How often the value of a random variable is at or below a certain value.
What is the probability that a group of five random digits will contain at least 3 even digits?

Among a group of people 10 percent are from New York City and 90 percent are not all people from New York City are under 18 years old See the rest of the question below?
Full Question: Among a group of people, 10% are from NYC and 90% are not. All people from NYC are under 18 years old, and 50% of those not from NYC are also under 18 years old. One person is chosen at random, and he or she is under 18. What is the probability that the person chosen is from NYC? Round your answer to two decimal places.
Poisson distribution the mean and standard deviation?
The Poisson distribution is a discrete distribution, with random variable k, related to the number events. The discrete probability function (probability mass function) is given as: f(k; L) where L (lambda) is the mean and square root of lambda is the standard deviation, as given in the link below: http://en.wikipedia.org/wiki/Poisson_distribution
