**Section 7**

**It is all quite Logical! - Not**

The deep end is a very good end to start with
logic.

*Task 1*

*I have two coins in my hand with a total
value of 30
cents. One of them is not a ten cent piece. What are the coins?*

Logic is about true and false. A cat is black
or not black.
A sock is white or black but cannot be all white and all black.

Here is a very cool example of logical
deduction.

*Task 2*

*There are three boxes and the labels on them
are all
incorrect. One box say it
contains only
white socks. Another box says it contains only black socks. The
third box says
it contains a mixture of block socks and white socks. Your task
is to choose
one sock from one box and relabel the boxes so they are all
correct. *
