In this lesson we will look at how we can represent probabilities as words and numbers

### Complementary events

In this lesson we will look at how we can calculate probabilities for complementary events

### Calculating probabilities

In this lesson we will look at calculating probabilities

### Theoretical probability and relative frequency

In this lesson we will look at calculating theoretical probabilities and relative frequencies

### Theoretical probability and relative frequency (Part 2)

In this lesson we will look in more detail at calculating theoretical probabilities and relative frequencies

### Comparing probabilities

In this lesson we will compare the probabilities of different events to see which is most likely

### Combined events and sample spaces (Part 1)

In this lesson we will represent the probabilities of combined events in a sample space

### Combined events and sample spaces (Part 2)

In this lesson we will look in more detail at how we can represent combined events and sample spaces

### Frequency trees

In this lesson we look at how we can represent combined events as frequency trees

### Calculating the probability of combined events

In this lesson we will look at how we can use area maps to calculate probabilities of combined events

### Combined Events and Tree Diagrams (Part 1)

In this lesson we will look at how we can represent combined events in a tree diagram

### Combined events and tree diagrams (Part 2)

In this lesson we will look at examples of when a tree diagram is more useful for combined events than a sample space diagram
