You need to use a table of standar normal distribution curve. There are different kind of tables (cumulative, fi function, stc..), but your anwer is:

The **empirical rule** allows you to make a quick assessment of probability without using a table. Just memorise these three numbers:

The same goes for values below

Remember every
