Question #6:

Mutually Exclusive Events

If event A and event B cannot occur jointly (simultaneously) P(A and B) =0, and B are called mutually exclusive events. So if a local zoo only had mammals and reptiles, the same space for types of zoo animals would be only mammals and reptiles.

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

choose the statements which are true for this scenario.

P(Mammal or Reptile)=1, or certain.

P(Mammal or reptile)=0, or impossible

P(Mammal and reptile)> 0, or possible

P(Mammal and reptile) < 0

P(Mammal and reptile) = 0, or impossible
