Statement

Young marine biologist Masha spent her summer in Primorye, diving and taking notes of what she saw on the seafloor. Later she found her records for one of the bays where she has been. These records were:

Help Masha to figure the minimum possible percentage of the seafloor inhabited by all three species simultaneously.

In the first example, shellfish live everywhere. Starfish and sea urchins each take 3/4 of the seafloor, which means that at least half of the seafloor is inhabited by shellfish, starfish and sea urchins simultaneously.

In the second example, there are areas where 2 out of 3 species live. But it's possible that there are no areas where all 3 species live.
