Worksheet Overview

Two-way tables can be used to display information relating to several different options and categories.


The following table shows the number of right and left-handed children in a school year group of 70 children.


  Boys Girls Total
Right 24 32 56
Left 4 10 14
Total 28 42 70


Notice how the totals add up in both directions.


There are 56 right-handed children.

There are 32 right-handed girls.


The probability that a child chosen at random is a right-handed girl is 32/70 = 16/35


Always remember to check that you have put the fraction into its simplest form.


Does that all make sense?  Then, let's get started.
