# Difference between classical approach and relative approach of probability with example?

###### Answered 2012-03-14 05:29:45

Classical approach has possible outcomes which are known with certainity ie sampling distribution is known.

Relative approach is an approach in which probability values are based on historical interest.

### What is the difference between relative frequency approximation of probability and the classical approach to probability?

Relative frequency approximation is conducting experiments and counting the number of times the event occurs divided by the total number of events. The classical approach is determine the number of ways the event can occur divided by the total number of events.

### What are the Three Approaches to finding a Probability?

1. subjective probability (intelligent guess) 2. relative frequency (in percent) 3. classical probability (in decimal)

### What is law of large numbers?

when a probability experiment is repeated a large number of times, the relative frequency probability of an outcome will approach its theoretical probability.

### How do you assign numerical values to indicate the probability of an event?

There are three main methods for assigning probabilities Following the classical definition of probability Using relative frequencies Using subjective probability

### Frequency approach for probability?

Well, that's not much of a question. Perhaps you are asking: What is the frequency interpretation of probability? This is called the classical interpretation of probability. Given n independent and identical trials with m occurrences of of a particular outcome, then the probability of this outcome, is equal to the limit of m/n as n goes to infinity. If you are asking: How can probabilities be estimated given data, based on frequency approach? A table is constructed, with intervals, and the number of events in each interval is calculated. The number of events divided by the total number of data is the relative frequency and an estimate of probability for the particular interval.

### Relationship between relative frequency and probability of an event?

The relative frequency is an estimate of the probability of an event.

### Is relative frequency similar to the concept of probability?

The relative frequency of of an event is one possible measure of its probability.

### What is the definitions of a theoretical probability?

To me, the theoretical probability is what is termed the classical probability. This says the probability is the number of ways an event can occur divided by the number of possible events. Forexample, flip a coin. The theoretical probability for heads is 1/2. However, flip a coin 10 times and you will probably not get 5/10 (or 1/2). Doing the actual experiment to determine the probability is called relative frequency approximation.

### What is the difference between the terms 'probability' and 'relative frequency'?

If an action is repeated n times and a certain event occurred b times then the ratio b/n is called the relative frequency.Where as theoretical probability is used to determine the number of ways that the event can occur if an experiment is repeated a large number of times.

### Does relative frequency probability use group information and apply it to single cases?

Yes, relative frequency probability uses group information and applies it to single cases.

### How do you calculate relative frequency probability?

You carry out an experiment repeatedly. Then the number of times that the selected even occurs divided by the total number of trials is the relative probability for that event.

### What is an example of relative frequency probability?

Flip a coin 1000 times, counting the number of 'heads' that occur. The relative frequency probability of 'heads' for that coin (aka the empirical probability) would be the count of heads divided by 1000. Please see the link.

### What differentiates a probability from a probability distribution?

A probability indicates the likely-hood that a particular event occurs out of a set number of observations or measurements. A probability distribution allows relative comparison of probability of an event with any other possible event.

### What did Darwin meant by fitness?

The relative probability of survival and reproduction for a genotype.

### Is relative frequency the same as probability?

If we are talking of an aleatory event, and its relative frequency obtained over a large number of trials, yes.

### Relative frequency formula?

Probability of event = relative frequency = f/nf is the frequency of the event occurence in a sample of n observances.

### What has the author Stefan Kaiser written?

Stefan Kaiser has written: 'Stefan Kaiser' 'Circumnominal relative clauses in classical Japanese' -- subject(s): Classical Grammar, Comparative and general Grammar, Grammar, Classical, Grammar, Comparative and general, Japanese language, Relative clauses 'Japanese Language Teaching in the Nineties'

### How are ratio and probability the same?

A ratio is a comparison of the relative size of two different things. Probability is the change that something will (or will not) occur. Probability can be expressed as a ratio of Yes to No (or, "will occur" to "won't occur"). That is, Probability is the relative size of Yes to No. So, if something is said to have a 60% Probability of occurring, what that is indicating is that, out of 100 tries, 60 will be the outcome indicated. While probability is usually expressed as a percentage, it is entirely possible to express it as a ratio. In the aforementioned example, a 60% Probability of occurrence could also be said to be a 60:40 (or, reduced, 3:2) ratio in favor of happening.

### How can a probability be estimated?

One way to estimate the probability of an event is to use a theoretical model to compare the relative likelihood of the event compared to all possible outcomes.

### What is the meaning of a relative frequency of 0?

Relative frequency of an event is the frequency of that event divided by the total number of observations. Therefore, a relative frequency of 0 implies the event has zero proportion (or probability).

### Difference between percent abundance and relative abundance?

The difference is that pBerceInTabundanCe is tHe percentage of it unlike relative abundance witch is just Numbers.
