**RELATIVE FREQUENCY**

- the probability of an event can be found by carrying out many trials and calculating the
**relative frequency or experimental probability**
- to calculate the relative frequency divide the number of times the event occurred during the experiment by the total number of trials done in the experiment
- ther higher the number of trials carried out the nearer the experimental probability will be to the true probabilty

**MUTUALLY EXCLUSIVE AND EXHAUSTIVE EVENTS**

- when the out come of event A can never happen the same time as event B then the events are said to be mutually exclusive
- when the probabilty of mutually exclusive events add up to 1 they are called exhaustive events
- if there is an event A the complementary event of A is event A not happening
