Question

A map of four countries is to be coloured with a different colour for each country. If six colours are

available. How many different ways are there to colour the map?​

Answer 1

Step-by-step explanation:

In mathematics, the four color theorem, or the four color map theorem, states that, given any separation of a plane into contiguous regions, producing a figure called a map, no more than four colors are required to color the regions of the map so that no two adjacent regions have the same color.
