Maths 2

2. Eva, Tamati, Noah and Jo are looking at these shapes.

Eva says, "Hey, the first shape is the odd one out."

Tamati says, "No, Eva, the second one’s the odd thing out!"

Noah says, "No, it’s the third one!"

Jo says, "Well you are ALL wrong! The last one is clearly the odd thing out."

Who is right and why? It will be the first one because the first one has no other faces.
