Final answer:

The question discusses random variables and probability distributions in mathematics, specifically the binomial distribution, hypergeometric distribution, uniform distribution, continuous random variables, and the standard normal distribution.

Step-by-step explanation:

The question pertains to the topic of probability distributions in mathematics, specifically involving random variables (RVs). A binomial distribution is a type of discrete distribution that results from a sequence of independent Bernoulli trials, where there is a fixed number (n) of these trials, the probability of success (p) in each trial is the same, and each trial results in just two possible outcomes: success or failure. The notation for a binomial random variable is X~B(n,p), with a mean (µ) of np and a standard deviation (o) of √npq. The probability of obtaining exactly x successes in n trials is captured by the formula P(X = x) = (n choose x)p^xq^(n-x), where q is the probability of failure (1-p).

On the other hand, a hypergeometric distribution is another discrete distribution but differs from the binomial distribution as the probability of success changes from trial to trial. This occurs when the trials are done without replacement, typically when you are sampling from a finite population. A uniform distribution, mentioned in the reference, is a type of continuous random variable that has equal probability across a certain range denoted by a < x < b. The probability density function (pdf) for a uniform distribution is constant over its range.

A continuous random variable is one which can take on any value within a range, often representing measurements, such as the height of trees. Lastly, the standard normal distribution is a special case of continuous distribution where the mean is 0 and the standard deviation is 1, denoted as Z~N(0,1).
