# 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.

### 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?

PMFAcronym Definition PMF Probability Mass Function PMF Preguntas Más Frecuentes (Frequently Asked Questions) PMF Probable Maximum Flood PMF Pierre Mendes-France (french former Prime Minister) #### 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.
