Interpreting Graphs
Body Mass Index (BMI) is a number calculated from your weight
and height. It roughly gives the percentage of your total weight that comes from fat.
The graph shows the BMI for different heights and weight.

Today we will be learning about probability.
The probability of an event occuring means the liklihood that it will happen.
P(Event Occurring) = No. of favourable outcomes No. of possible outcomes
Probability is measured usually as a fraction or a decimal between 0 and 1.
