A tropical fish hobbist had six different types of fish: Alphas, Betas, Certas, Deltas, Epsalas, and Fetas, which shall henceforth be designated by A, B, C, D, E, and F, respectively. Because of predator-prey relatinships, water conditions, and size, some fish can be kept in the same tank. The following table shows which fish cannot be together:
|Cannot be with||B, C||A ,C, E||A, B, D, E||C, F||B, C, F||D, E|
We will use a graph to help us answer this question. Below you will see an uncolored graph that describes this situation. Can you figure out what each vertex represents? each edge?
