Use relative frequency to find probabilities
Relative frequencies are sometimes called experimental probalities. They are used to determine probablities based on an experiment or a situation. For instance if we toss a coin 100 times, and get 60 heads and 40 tails, we can estimate that the probabiltity of getting a heads in this situation is 3/5
So Relative frequency = Number of successful trials/total number of trials.
Example:
A survey of 100 people was taken to find out whether they were lefthanded or righthanded. 12 people said they were lefthanded.
Using our formula for relative frequency, we take the number of successful trials  i.e. the number of people who are lefthanded. Then divide this number by the total number of trials i.e. the total number of people
so the relative frequency is 12/100 = 3/25
