Answer:
The correct option is C.
Step-by-step explanation:
According to the question given in the attached picture:
Event A = a customer buys a mouse
Event B = A customer buys a bird
P(A or B) = 0.25
Now have a look at the probability P(A or B). Here or means either..Its means that the customer will purchase either a mouse or a bird. That means that there is 0.25 or 25% probability that the customer will purchase either a mouse or a bird. In this case there are only 3 choices, which are: the customer will either purchase a mouse, a bird or a reptile because the pet store has only these three possible outcomes. We are not told that how much of each animal they have. Thus the probability that the customer will either purchase either a mouse or a bird is 0.25 or 25%. That means that the probability of either purchasing a mouse or a bird is added together which is 0.25 or 25%
Thus the correct option is C....
