An event A and event B cannot occur jointly (simultaneously), P (A and) -0, ad A and B are called mutually exclusive events.So, if a local zoo only has mammals and reptiles, the sample space for types of zoo animals would be only mammals and reptiles.

Based on the zoo that had only mammals and reptiles, this ample space for this question contains only Mammals and Reptiles.
