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)
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.
Why is relative frequency different to probability?
It is not! It is one measure of probability.
How do you convert a beta probability density function to a beta frequency distribution?
probability density distribution
Is it true that probability is a long term frequency?
Yes
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.

If a die is rolled 375 times and 5 occurs 80 times what is the probability of rolling a 5?
The probability of rolling a 5, based on the information given, is 80/375 or 16/75. Your problem describes a relative frequency approximation of probability.

Is relative frequency similar to the concept of probability?
The relative frequency of of an event is one possible measure of its probability.
Why is relative frequency different to probability?
It is not! It is one measure of probability.
Relationship between relative frequency and probability of an event?
The relative frequency is an estimate of the probability of an event.
What is the calculated probability based on relative frequency?
It is the empirical or experimental probability.
Is probability tree the same as a frequency tree?
No, it is not.
What is the formula for expected frequency?
You need to know the probability of the event in question. Then the expected frequency for that event occurring is that probability times the number of times the experiment was repeated.
