What is the Bernoulli trial?

In the theory of probability and statistics, a Bernoulli trial (or binomial trial) is a random experiment with exactly two possible outcomes, "success" and "failure", in which the probability of success is the same every time the experiment is conducted.
A.

What is the Bernoulli principle?

Bernoulli's principle, physical principle formulated by Daniel Bernoulli that states that as the speed of a moving fluid (liquid or gas) increases, the pressure within the fluid decreases. Since the speed is greater in the narrower pipe, the kinetic energy of that volume is greater.
  • What is the Venturi meter?

    VENTURI METERS. Venturi meters are flow measurement instruments which use a converging section of pipe to give an increase in the flow velocity and a corresponding pressure drop from which the flowrate can be deduced. They have been in common use for many years, especially in the water supply industry.
  • How does the Bernoulli principle related to flight?

    Bernoulli's principle: Bernoulli's principle helps explain that an aircraft can achieve lift because of the shape of its wings. They are shaped so that that air flows faster over the top of the wing and slower underneath. Fast moving air equals low air pressure while slow moving air equals high air pressure.
  • Why does pressure increase with decrease in velocity?

    So when the area is reduced, since the fluid is incompressible, its density won't change, so velocity has to increase. Fluid exiting from a nozzle, decrease in Pressure:Now Total energy of each delta element of fluid has to remain constant through out out the flow, hence we have the Bernoulli's principle.
B.

What is the binomial process?

A binomial process is a random counting system where there are n independent identical trials, each one of which has the same probability of success p, which produces s successes from those n trials (where 0 ≤ s ≤ n and n > 0 obviously). The simplest example of a binomial process is the toss of a coin.
  • Is a Poisson distribution discrete or continuous?

    I have a few data sets where response variables are continuous, but resemble a poisson distribution rather than a normal distribution. However, the poisson distribution is a discrete distribution and is usually concerned with numbers or counts.
  • What is NP in statistics?

    An NP chart is a data analysis technique for determining if a measurement process has gone out of statistical control. It is sensitive to changes in the number of defective items in the measurement process. The “NP” in NP charts stands for the np (the mean number of successes) of a binomial distribution.
  • What is the use of Bernoulli distribution?

    The Bernoulli distribution is a discrete distribution having two possible outcomes labelled by and in which ("success") occurs with probability and ("failure") occurs with probability , where . It therefore has probability density function.
C.

What is the renewal process?

A renewal process is an idealized stochastic model for events that occur randomly in time (generically called renewals or arrivals). The basic mathematical assumption is that the times between the successive arrivals are independent and identically distributed.
  • What does PMFS stand for?

  • Is PDF and PMF the same thing?

    Thus, the interpretation of the CDF is the same whether we have a discrete or continuous variable (read pdf or pmf), but the definition is slightly different. tl;dr- PMF and PDF are almost the same, but one is for discrete distributions and one is for continuous distributions.
  • What is a probability mass function?

    The “discrete” part means that there's a set number of outcomes. For example, you can only roll a 1,2,3,4,5, or 6 on a die. Its counterpart is the probability density function, which gives probabilities for continuous random variables.
