Since only 2 beads can be used, Red is automatically out as it requires at least 1 G and 1 B to be between 2 Rs
Given the condition that there can be no beads of the same colour adjacent to each other, we can have 1 of 2 arrangements: Either B in the corner or G in the corner
So only 2 arrangements are possible here (This can be concluded without actually drawing the grid, so a must attempt question)

The question is "The total number of possible congurations using beads of only two colours is:"

##### Hence, the answer is, " 2"
