Here is a diagram of 6 islands. The islands are in 2 rows of 3.
Draw 3 of the islands with 3 bridges leading from them to another island. Draw 2 of the islands with 2 bridges leading from them to another island. Draw 1 island with only one bridge leading from it.
See how many different ways you can draw these six islands and their bridges.
