The frequency approach or experimental probability involves the estimation of the probability of an outcome as the proportion of "successful" outcomes in repeated trials.
I put "successful" in quotes because in epidemiology, a "successful" outcome is often a person catching a disease or infection and possibly dying as a result. I am not sure if anyone would consider that a success!

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.
Is relative frequency similar to the concept of probability?
The relative frequency of of an event is one possible measure of its probability.
Relationship between relative frequency and probability of an event?
The relative frequency is an estimate of the probability of an event.
Which approach to probability requires equally likely outcomes?
The modelling of a probability distribution function for an event from a theoretical approach.
What is the calculated probability based on relative frequency?
It is the empirical or experimental 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.
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.
1 Using the relative frequency approach to probability if a country is selected at random what is the probability it will be in Europe?
1/7 or approximately .142 There are 7 continents and you are choosing only 1.
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.
Which approach to probability requires equally likely outcomes?
The modelling of a probability distribution function for an event from a theoretical approach.
What is the calculated probability based on relative frequency?
It is the empirical or experimental probability.
Difference between classical approach and relative approach of probability with example?
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.
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.
