Solution
All options are corrects. Becuase horse can be housed in a single placed. So event A and B are mutually exclusive. Since if a horse did not house in barn stall, horse housed in pipe pens or pasture so A and B are complement to each other. Since A and B mutually exclusive so
P(A and B)=0
So
P(A or B)=P(A)+P(B)
